Although less well-documented, Morocco's earliest historical periods were dominated by Berber groups and kingdoms, up to the Berber kingdom of Mauretania.^[16] In the 7th or 8th century BC the Phoenicians founded a colony of Lixus on the Atlantic coast, which later came under Carthaginian, Mauretanian, and eventually Roman control.^[17][18] Other important towns such as Tingis (present-day Tangier) and Sala (Chellah) were founded and developed by Phoenicians or Mauretanian Berbers.^[19]: 69 The settlement of Volubilis was the traditional capital of the Mauretanian kingdom from the second century BC onward, though it may have been founded as early as the third century BC.^[20] Under Mauretanian rule its streets were laid out in a grid plan and may have included a palace complex and fortified walls.^{[20][16]: 32} The influence of Punic (Carthaginian) culture in the city is archaeologically attested by Punic stelae and the remains of a Punic temple.^[20] The Mauretanian king Juba II (r. 25 BC–23 AD), a client king of Rome and a promoter of late Hellenistic culture, built a palace in Lixus that was based on Hellenistic models.^{[16]: 43–44 [18]}

Roman settlement and construction was much less extensive in the territory of present-day Morocco, which was on the edge of the empire, than it was in nearby regions like Hispania or Africa (present-day Tunisia). The most significant cities, and the ones most directly influenced by Roman culture, were Tingis, Volubilis, and Sala.^{[19]: 67–68} Large-scale Roman architecture was relatively rare; for example, there is only one known amphitheater in the region, at Lixus.^[19]: 68 Volubilis, the most inland major city, became a well-developed provincial Roman municipium and its ruins today are the best-preserved Roman site in Morocco. It included aqueducts, a forum, bath complexes, a basilica, the Capitoline Temple, and a triumphal arch dedicated to the emperor Caracalla and his mother in 216–217. The site has also preserved a number of fine Roman mosaics.^[20][21] It continued to be an urban center even after the end of Roman occupation in 285, with evidence of Latin Christian, Berber, and Byzantine (Eastern Roman) occupation.^[22]: 53

In the early 8th century the region became steadily integrated into the emerging Muslim world, beginning with the military incursions of Musa ibn Nusayr and becoming more definitive with the advent of the Idrisid dynasty at the end of that century.^[23] The arrival of Islam was extremely significant as it developed a new set of societal norms (although some of them were familiar to Judeo-Christian societies) and institutions which therefore shaped, to some extent, the types of buildings being built and the aesthetic or spiritual values that guided their design.^{[24][25][26][27]}

The Idrisids founded the city of Fes, which became their capital and the major political and cultural center of early Islamic Morocco.^[19][28] In this early period Morocco also absorbed waves of immigrants from Tunisia and al-Andalus (Muslim-ruled Spain and Portugal), who brought in cultural and artistic influences from their home countries.^[23][1] The earliest well-known Islamic-era monuments in Morocco, such as the al-Qarawiyyin and Andalusiyyin mosques in Fes, were built in the hypostyle form and made early use of the horseshoe or "Moorish" arch.^[2][29] These reflected early influences from major monuments like the Great Mosque of Kairouan and the Great Mosque of Cordoba.^[30] In the 10th century much of northern Morocco came directly within the sphere of influence of the Umayyad Caliphate of Cordoba, with competition from the Fatimid Caliphate further east.^[23] Early contributions to Moroccan architecture from this period include expansions to the Qarawiyyin and Andalusiyyin mosques and the addition of their square-shafted minarets, the oldest surviving mosques in Morocco, which anticipate the standard form of later Moroccan minarets.^{[29][2][31]: 126}

The collapse of the Cordoban caliphate in the early 11th century was followed by the significant advance of Christian kingdoms into Muslim al-Andalus and the rise of major Berber empires in Morocco. The latter included first the Almoravids (11th–12th centuries) and then the Almohads (12th–13th centuries), both of whom also took control of remaining Muslim territory in al-Andalus, creating empires that stretched across large parts of western and northern Africa and into Europe.^[30] This period is considered one of the most formative stages of Moroccan and Moorish architecture, establishing many of the forms and motifs that were refined in subsequent centuries.^{[2][32][30][33]} These two empires were responsible for establishing a new imperial capital at Marrakesh and the Almohads also began construction of a monumental capital in Rabat.

The Almoravids adopted the architectural developments of al-Andalus, such as the complex interlacing arches of the Great Mosque in Cordoba and of the Aljaferia palace in Zaragoza, while also introducing new ornamental techniques from the east such as muqarnas ("stalactite" or "honeycomb" carvings).^[32][34] The Almohad Kutubiyya and Tinmal mosques are often considered the prototypes of later Moroccan mosques.^[32][2] The monumental minarets (e.g. the Kutubiyya minaret, the Giralda of Seville, and the Hassan Tower of Rabat) and ornamental gateways (e.g. Bab Agnaou in Marrakesh, and Bab Oudaia and Bab er-Rouah in Rabat) of the Almohad period also established the overall decorative schemes that became recurrent in these architectural elements thenceforth. The minaret of the Kasbah Mosque of Marrakesh was particularly influential and set a style that was repeated, with minor elaborations, in the following Marinid period.^[35][32][2] The Almoravids and Almohads also promoted the tradition of establishing garden estates in the countryside of their capital, such as the Menara Garden and the Agdal Gardens on the outskirts of Marrakesh. In the late 12th century the Almohads created a new fortified palace district, the Kasbah of Marrakesh, to serve as their royal residence and administrative center. These traditions and policies had earlier precedents in al-Andalus – such as the creation of Madinat al-Zahra near Cordoba – and were subsequently repeated by future rulers of Morocco.^{[35][30][2][36]}

The Berber Marinid dynasty that followed was also important in further refining the artistic legacy established by their predecessors. Based in Fes, they built monuments with increasingly intricate and extensive decoration, particularly in wood and stucco.^[2] They were also the first to deploy extensive use of zellij (mosaic tilework in complex geometric patterns).^[3] Notably, they were the first to build madrasas, a type of institution which originated in Iran and had spread west.^[2] The madrasas of Fes, such as the Bou Inania, al-Attarine, and as-Sahrij madrasas, as well as the Marinid madrasa of Salé and the other Bou Inania in Meknes, are considered among the greatest architectural works of this period.^[37][4][2] While mosque architecture largely followed the Almohad model, one noted change was the progressive increase in the size of the sahn or courtyard, which was previously a minor element of the floor plan but which eventually, in the subsequent Saadian period, became as large as the main prayer hall, and sometimes larger.^[38] Like the Almohads before them, the Marinids created a separate palace-city for themselves; this time, outside Fes. Later known as Fes Jdid, this new fortified citadel had a set of double walls for defense, a new Grand Mosque, a vast royal garden to the north known as el-Mosara, residences for government officials, and barracks for military garrisons.^[36][39] Later on, probably in the 15th century, a new Jewish quarter was created on its south side, the first mellah in Morocco, prefiguring the creation of similar districts in other Moroccan cities in later periods.^[40][41]

The architectural style under the Marinids was very closely related to that found in the Emirate of Granada, in Spain, under the contemporary Nasrid dynasty.^[2] The decoration of the famous Alhambra is thus reminiscent of what was built in Fes at the same time. When Granada was conquered in 1492 by Catholic Spain and the last Muslim realm of al-Andalus came to an end, many of the remaining Spanish Muslims (and Jews) fled to Morocco and North Africa, further increasing the Andalusian influence in these regions in subsequent generations.^[4]

After the Marinids came the Saadian dynasty, which marked a political shift from Berber-led empires to sultanates led by Arab sharifian dynasties. Artistically and architecturally, however, there was broad continuity and the Saadians are seen by modern scholars as continuing to refine the existing Moroccan-Moorish style, with some considering the Saadian Tombs in Marrakesh as one of the apogees of this style.^{[38]: 194–196 [2]: 422}

Starting with the Saadians and continuing with the Alawis (their successors and the reigning monarchy today), Moroccan art and architecture is portrayed by modern (Western) scholars as being relatively conservative; meaning that it continued to reproduce the existing style with high fidelity but did not introduce major new innovations.^{[2]: 421–422 [42][38]: 194} The Saadians, especially under the sultans Abdallah al-Ghalib and Ahmad al-Mansur, were extensive builders and benefitted from great economic resources at the height of their power in the late 16th century. In addition to the Saadian Tombs, they also built the Ben Youssef Madrasa and several major mosques in Marrakesh including the Mouassine Mosque and the Bab Doukkala Mosque. These two mosques are notable for being part of larger multi-purpose charitable complexes including several other structures like public fountains, hammams, madrasas, and libraries. This marked a shift from the previous patterns of architectural patronage and may have been influenced by the tradition of building such complexes in Mamluk architecture in Egypt and the külliyes of Ottoman architecture.^{[35]: 367 [43]} The Saadians also rebuilt the royal palace complex in the Kasbah of Marrakesh for themselves, where Ahmad al-Mansur constructed the famous El Badi Palace (built between 1578 and 1593) which was known for its superlative decoration and costly building materials including Italian marble.^[35][38]

The Alawis, starting with Moulay Rashid in the mid-17th century, succeeded the Saadians as rulers of Morocco and continue to be the reigning monarchy of the country to this day. As a result, many of the mosques and palaces standing in Morocco today have been built or restored by the Alawis at some point or another.^{[4][35][28][2]: 383–422 [42]} Ornate architectural elements from Saadian buildings, most famously from their lavish El Badi Palace in Marrakesh, were also stripped and reused in buildings elsewhere during the reign of Moulay Isma'il (1672–1727).^[38] Moulay Isma'il is also notable for having built a vast imperial palace complex – similar to previous palace-citadels but on a grander scale than before – in Meknes, where the remains of his monumental structures can still be seen today.^{[44][36]: 265–267} In his time Tangier was also returned to Moroccan control in 1684, and much of the city's current Moroccan and Islamic architecture dates from his reign or after.^[45][4]

In 1765 Sultan Mohammed Ben Abdallah (Moulay Ismail's grandson) started the construction of a new port city called Essaouira (formerly Mogador), located along the Atlantic coast as close as possible to his capital at Marrakesh, to which he tried to move and restrict European trade.^[36]: 264 He hired European architects to design the city, resulting in a relatively unique Moroccan-built city with Western European architecture, particularly in the style of its fortifications. Similar coastal fortifications or bastions, usually known as a sqala, were built at the same time in other port cities like Anfa (present-day Casablanca), Rabat, Larache, and Tangier.^[2]: 409 Up until the late 19th century and early 20th century, the Alawi sultans and their ministers continued to build beautiful palaces, many of which are now used as museums or tourist attractions, such as the Bahia Palace in Marrakesh, the Dar Jamaï in Meknes, and the Dar Batha in Fes.^[3][11]

In the 20th century, Moroccan architecture and cities were also shaped by the period of French colonial control (1912–1956) as well as Spanish colonial rule in the north of the country (1912–1958). This era introduced new architectural styles such as Art Nouveau, Art Deco, and other modernist styles, in addition to European ideas about urban planning imposed by colonial authorities.^[46] The European architects and planners also drew on traditional Moroccan architecture to develop a style sometimes referred to as Neo-Mauresque (similar to Neo-Moorish) or Arabisant ("Arabizing"), blending contemporary European architecture with a pastiche of traditional Moroccan architecture, with the encouragement of the French resident general Hubert Lyautey.^[11][12][10]

The French moved the capital to Rabat and founded a number of Villes Nouvelles ("New Cities") next to the historic medinas (old walled cities) to act as new administrative centers, which have since grown beyond the old cities. In particular, Casablanca was developed into a major port and quickly became the country's most populous urban center.^[23] As a result, the city's architecture became a major showcase of Art Deco and colonial Mauresque architecture. Notable examples include the civic buildings of Muhammad V Square (Place Mohammed V), the Cathedral of Sacré-Coeur, the Art Deco-style Cinéma Rialto, the Neo-Moorish-style Mahkamat al-Pasha in the Habous district.^{[11][47][48][49]} Similar architecture also appeared in other major cities like Rabat and Tangier, with examples such as the Gran Teatro Cervantes in Tangier and the Bank al-Maghrib and post office buildings in downtown Rabat.^[50][51][52] Elsewhere, the smaller southern town of Sidi Ifni is also notable for Art Deco architecture dating from the Spanish occupation.^[53]

Elie Azagury became the first Moroccan modernist architect in the 1950s.^[54][55] In the later 20th century and into the 21st century, contemporary Moroccan architecture also continued to pay tribute to the country's traditional architecture. In some cases, international architects were recruited to design Moroccan-style buildings for major royal projects such as the Mausoleum of Mohammed V in Rabat and the massive Hassan II Mosque in Casablanca.^[56][13] The monumental new gates of the Royal Palace in Fez, built in 1969–1971, also made use of traditional Moroccan craftsmanship.^[3] The new train stations of Marrakesh and Fes are examples of traditional Moroccan forms being adapted to modern architecture.^[57] The traditional Moroccan style or imitations of it have also been employed frequently in the design of new hotels.^[12]

Modernist architecture has also continued to be used, exemplified by buildings like the Sunna Mosque (1966) and the Twin Center (1999) in Casablanca. More recently, some 21st-century examples of major or prestigious architecture projects include the extension of Marrakesh's Menara Airport (completed in 2008),^[58] the National Library of Morocco in Rabat (2008), the award-winning High-Speed Train Station in Kenitra (opened in 2018),^[59][60] the Finance City Tower in Casablanca (completed in 2019 and one of the tallest buildings in Morocco),^[61] and the new Grand Theatre of Rabat by Zaha Hadid (due to be completed in late 2019).^[62][63]

As with the rest of the Mediterranean world, the culture and monuments of Classical Antiquity and of Late Antiquity had an important influence on the architecture of the Islamic world that came after them. In Morocco, the former Roman city of Volubilis acted as the first Idrisid capital before the foundation of Fes.^[28][19] The columns and capitals of Roman and early Christian monuments were frequently re-used as spolia in the early mosques of the region – although this was far less common in Morocco, where Roman remains were far sparser.^[36]: 43 Later Islamic capitals developed from these models in turn.^[2][64] In other examples, the vegetal and floral motifs of Late Antiquity formed one of the bases from which Islamic-era arabesque motifs were derived.^[65][2] The iconic horseshoe arch or "moorish" arch, which became a regular feature of Moroccan and Moorish architecture, also had some precedents in Byzantine and Visigothic buildings.^{[2]: 163–164 [5]} Lastly, another major legacy of Greco-Roman heritage was the continuation and proliferation of public bathhouses, known as hammams, across the Islamic world – including Morocco – which were closely based on Roman thermae and took on added social roles.^[2][66][67]

The arrival of Islam with Arab conquerors from the east in the early 8th century brought about social changes which also required the introduction of new building types such as mosques. The latter followed more or less the model of other hypostyle mosques which were common across much of the Islamic world at the time.^[30][36] The traditions of Islamic art also introduced certain aesthetic values, most notably a general preference for avoiding figurative images due to a religious taboo on icons or worshipped images.^[68][69] This aniconism in Islamic culture caused artists to explore non-figural art, and created a general aesthetic shift toward mathematically-based decoration, such as geometric patterns, as well as other relatively abstract motifs like arabesques.^[70] While figurative images did continue to appear in Islamic art, by the 14th century these were generally absent in the architecture of the western regions of the Islamic world like Morocco.^[65] Some figural images of animals still appeared occasionally in royal palaces, such as the sculptures of lions and leopards in the monumental fountain of a former Saadian palace in the Agdal Gardens.^[71][72]

Aside from the initial changes brought about by the arrival of Islam, Moroccan culture and architecture continued afterwards to adopt certain ideas and imports from the eastern parts of the Islamic world. These include some of the institutions and building types that became characteristic of the historic Muslim world. For example, bimaristans, historical equivalents of hospitals, first originated further east in Iraq, with the first one being built by Harun al-Rashid (between 786 and 809).^[73] They spread westward and first appeared in Morocco around the late 12th century when the Almohads founded a maristan in Marrakesh.^[74][75] Madrasas, another important institution, first originated in Iran in the early 11th century under Nizam al-Mulk, and were progressively adopted further west.^[2][76][77] The first madrasa in Morocco (Madrasat as-Saffarin) was built in Fes by the Marinids in 1271, and madrasas further proliferated in the 14th century.^[2][78] In terms of decorative motifs, muqarnas, a notable feature of Moroccan architecture introduced in the Almoravid period in the 12th century,^[2]: 237 also originated at first in Iran before spreading to the west.^[32][34]

The culture of Muslim-controlled Al-Andalus, which existed across much of the Iberian Peninsula to the north between 711 and 1492, also had close influence on Moroccan history and architecture in a number of ways – and was in turn influenced by Moroccan cultural and political movements. Jonathan Bloom, in his overview of western Islamic architecture, remarks that he "treats the architecture of North Africa and the Iberian Peninsula together because the Straits of Gibraltar were less of a barrier and more of a bridge."^[36]: 13

In addition to the geographic proximity of the two regions, there were many waves of immigration from Al-Andalus to Morocco of both Muslims and Jews. One of the earliest waves were the Arab exiles from Cordoba who came to Fes after a failed rebellion in the early 9th century.^[79]: 44 This population transfer culminated in the waves of refugees that came after the fall of Granada in 1492, including many former elites and members of the Andalusi educated classes.^[4] These immigrants played important roles in Moroccan society. Among other examples, it was the early Arab exiles from Cordoba who gave the Andalusiyyin quarter of Fes its name^[28] and it was Andalusi refugees in the 16th century who rebuilt and expanded the northern city of Tétouan.^[4]

The period of the Umayyad Emirate and Caliphate in Cordoba, which marked the peak of Muslim power in Al-Andalus, was an especially crucial era which saw the construction of some of the region's most important early Islamic monuments. The Great Mosque of Cordoba is frequently cited by scholars as a major influence on the subsequent architecture of the western regions of the Islamic world due to both its architectural innovations and its symbolic importance as the religious heart of the powerful Cordoban Caliphate.^{[80][5][81][30]: 281–284} Many of its features, such as the ornamental ribbed domes,^{[2]: 149–151} the minbar, and the polygonal mihrab chamber, would go on to be recurring models of later elements in the Islamic architecture of the wider region.^[30]: 284 Likewise, the decorative layout of the Bab al-Wuzara' gateway, the original western gate of the mosque, demonstrates many of the standard elements that recur in the gateways and mihrabs of subsequent periods: namely, a horseshoe arch with decorated voussoirs, a rectangular alfiz frame, and an inscription band.^{[2]: 165–170} Georges Marçais (an important 20th-century scholar on this subject^[82]: 279) also traces the origins of some later architectural features directly to the complex arches of Al-Hakam II's 10th-century expansion of the mosque, namely the polylobed arches found throughout the region after the 10th century and the sebka motif which became ubiquitous in Moroccan architecture after the Almohad period (12th-13th centuries).^[2] Moreover, for much of the 10th century the Caliphate of Cordoba held northern Morocco in its sphere of influence. During this period Caliph Abd ar-Rahman III contributed to the architecture of Fes by sponsoring the expansion of the Qarawiyyin Mosque.^[36] The same caliph also oversaw the construction of the first minaret of Cordoba's mosque, whose shape – a square-based shaft with a secondary lantern tower above it – some scholars see as precursor to other minarets in al-Andalus and Morocco.^[36]: 63 Around the same time, in 756, he also sponsored the construction of a similar (though simpler) minaret for the Qarawiyyin Mosque, while the Umayyad governor of Fes sponsored the construction of a similar minaret for the Al-Andalusiyyin Mosque across the river.^{[36]: 63–66}

Starting in the 11th century, the Berber-led Almoravid and Almohad empires, which were based in Morocco but also controlled al-Andalus, were instrumental in combining the artistic trends of both North Africa and al-Andalus, leading to what eventually became the definitive "Hispano-Moorish" or Andalusi-Maghribi style of the region.^{[30]: 276–328} The famous Almoravid Minbar in Marrakesh, commissioned from a workshop of craftsmen in Cordoba, is one of the examples illustrating this cross-continental sharing of art and forms.^[30][83] These traditions of Moorish art and architecture were continued in Morocco (and the wider Maghreb) well after the end of Muslim rule on the Iberian Peninsula.^[2][36][38]

The Amazigh peoples (commonly called "Berbers" in English) are a linguistically and ethnically diverse group of peoples who constitute the indigenous (pre-Arab) inhabitants of North Africa. They continue to represent a large part of the population in Morocco.^[85] In addition to any local traditions of architecture, Amazigh peoples adapted the forms and ideas of Islamic architecture to their own conditions,^[9][86] while the patronage of Amazigh dynasties contributed in turn to the formation of Western Islamic art, particularly during their political domination of the region over the centuries of Almoravid, Almohad, and Marinid rule.^{[6][87][7][32]: 28–30}

Given the intermixing of peoples and settlements in the region over the centuries, it is not always easy to separate Amazigh and non-Amazigh architectural features; however, there are architectural types and features associated with predominantly Amazigh areas of Morocco (particularly the rural Atlas mountains and Saharan regions) which are sufficiently distinctive to constitute their own characteristic styles.^[7] Because the relevant structures are made of rammed earth or mud-brick, which requires regular maintenance for preservation, the existing examples can rarely be dated reliably past the 19th or even 20th centuries.^[87] Nonetheless, some characteristics of Berber architecture in North Africa – such as the regional forms of mosques – have been established for roughly a millennium.^[7]

Structures such as agadirs (fortified granaries) and qsūr or qsars (fortified villages; often spelled ksar in singular and ksour in plural) are prominent traditional features of Amazigh architecture in Morocco.^[88] Likewise, the landscapes of the Atlas mountains and oases regions of Morocco are marked by numerous kasbahs – or tighremt in Amazigh languages^[86] – which in this case refers to tall, fortified structures acting as forts, warehouses, and/or fortified residences.^[87][7] These can in turn be decorated with local geometric motifs carved into the mud-brick exteriors.^[87][7]

The Treaty of Fes established the French Protectorate in 1912. The French resident general Hubert Lyautey appointed Henri Prost to oversee the urban development of cities under his control.^[90][91] One important policy with long-term consequences was the decision to largely forego redevelopment of existing historic cities and to deliberately preserve them as sites of historic heritage, still known today as the "medinas". Instead, the French administration built new modern cities (the Villes Nouvelles) just outside the old cities, where European settlers largely resided with modern Western-style amenities. This was part of a larger "policy of association" adopted by Lyautey which favored various forms of indirect colonial rule by preserving local institutions and elites, in contrast with other French colonial policies that favored "assimilation".^[89][92] The desire to preserve historic cities was also consistent with one of the trends in European ideas about urban planning at the time which argued for the preservation of historic cities in Europe – ideas which Lyautey himself favored.^[91] In April 1914, the colonial government promulgated a dahir for the "arrangement, development, and extension of urban plans, easements, and road tolls".^[93][94] This dahir included building standards which directly affected the architecture at that time, as follows:

1. Buildings could not be higher than four stories.
2. Land use regulation required twenty percent of a planned area to be courtyards or gardens.
3. Balconies must not overlook neighboring residences.
4. Roofs of all buildings should be flat.

The building regulations maintained the country's pre-existing architectural features and balanced the rapid urbanization. Nonetheless, while this policy preserved historic monuments, it also had other consequences in the long-term by stalling urban development in these heritage areas and causing housing shortages in some areas.^[89] It also suppressed local Moroccan architectural innovations, as for example in the medina of Fez where Moroccan residents where required to keep their houses – including any newly built houses – in conformity with what the French administration deemed to be the historic indigenous architecture.^[92] Scholar Janet Abu-Lughod has argued that these policies created a kind of urban "apartheid" between the indigenous Moroccan urban areas – which were forced to remain stagnant in terms of urban development – and the new planned cities which were mainly inhabited by Europeans and which expanded to occupy lands outside the city which were formerly used by Moroccans.^[95][96][89] This separation was partly softened by wealthy Moroccans who started moving into the Villes Nouvelles during this period.^[91]

In some cases French officials removed or remodelled more recent pre-colonial Moroccan structures which had been visibly influenced by European styles in order to erase what they deemed as foreign or non-indigenous interference in Moroccan architecture.^[92] In turn, French architects constructed buildings in the new cities that conformed to modern European functions and layouts but whose appearance was heavily blended with local Moroccan decorative motifs, resulting in a Mauresque^[11] or Neo-Moorish-style architecture. This was especially evident in some cities like the capital of Rabat, where grand new administrative buildings were designed in this style alongside European-style boulevards.^[89] In some cases, the French also inserted Moroccan-looking structures in the fabric of the old cities, such as the Bab Bou Jeloud gate in Fes (completed in 1913^[97]) and the nearby Collège Moulay Idriss (opened in 1914).^[98][92] The new French-built cities also introduced more modernist styles such as Art Deco. This heritage is especially notable in Casablanca,^[99] which became the main port city and the country's largest city during this period.^[23]

One of the most common types of construction in Morocco was rammed earth, an ancient building technique found across the Near East, Africa, and beyond.^{[100][101][102]} It is also known as "pisé" (from French) or "tabia" (from Arabic).^[3] The ramparts of Fes, Marrakesh, and Rabat, for example, were made with this process, even though some notable structures (like monumental gates) were also built in stone. It generally made use of local materials and was widely used thanks to its low cost and relative efficiency.^[100] This material consisted of mud and soil of varying consistency (everything from smooth clay to rocky soil) usually mixed with other materials such as straw or lime to aid adhesion. The addition of lime also made the walls harder and more resistant overall, although this varied locally as some areas had soil which hardened well on its own while others did not.^[3] (For example, the walls of Fes and nearby Meknes contain up to 47% lime versus around 17% in Marrakesh and 12% in Rabat.^[103]) The technique is still in use today, though the composition and ratio of these materials has continued to change over time as some materials (like clay) have become relatively more costly than others (like gravel).^[3][1]: 80

The walls were built from bottom to top one level at a time. Workers pressed and packed in the materials into sections ranging from 50 and 70 cm in length that were each held together temporarily by wooden boards. Once the material was settled, the wooden restraints could be removed and the process was repeated on top of the previously completed level.^[101][103] This process of initial wooden scaffolding often leaves traces in the form of multiple rows of little holes visible across the face of the walls.^[1] In many cases walls were covered with a coating of lime, stucco, or other material to give them a smooth surface and to better protect the main structure.^[3]

This type of construction required consistent maintenance and upkeep, as the materials are relatively permeable and are more easily eroded by rain over time; in parts of Morocco, (especially near the Sahara) kasbahs and other structures made with a less durable composition (typically lacking lime) can begin to crumble apart in less than a couple of decades after they've been abandoned.^[3][104] As such, old structures of this type remain intact only insofar as they are continuously restored; some stretches of wall today appear brand new due to regular maintenance, while others are crumbling.

In addition to rammed earth, brick and (especially in desert regions) mudbrick were also common types of materials for the construction of houses, civic architecture, and mosques.^{[2][105][106]} Many medieval minarets, for example, are made in brick, in many cases covered with other materials for decoration.^[2][105] Stone masonry was also used in many notable monuments, especially in the Almohad period. The monumental Almohad gates of Bab Agnaou, Bab er-Rouah, and the main gate of the Udayas Kasbah (Bab Oudaia) made extensive use of carved stone.^[2][32] The major Almohad minarets of the same period demonstrate the relative variability in construction material and methods, depending on the region and the demands of the structure: the minaret of the Kutubiyya Mosque is built in rubble masonry using sandstone, the Giralda of Seville (in Spain) was made in local brick, the massive but unfinished Hassan Tower in Rabat was made in stone, and the minaret of the Kasbah Mosque in Marrakesh was made with a base of rubble stone and a main shaft of brick.^{[2]: 209–211}

Wood was also extensively used, but mostly for ceilings and other elements above eye level such as canopies and upper galleries. Many buildings such as mosques and mausoleums have sloped wood-frame or artesonado-like ceilings, known locally as berchla or bershla,^[38][107] often visually enhanced by the use of geometric patterns in their arrangement, sculpting, and painted decoration.^[2] Many doorways, street fountains, and mosque entrances are also highlighted with sculpted wood canopies which were characteristic of Moroccan and Moorish architecture.^[2] Especially from the Marinid period onward, sculpted wood became a major component of architectural decoration.^[4][2]

•

•

Wood generally came from Moroccan cedar trees,^[38][3][31] still highly valued today, which once grew abundantly on mountain slopes across the country but are now partly endangered and limited to forests of the Middle Atlas.^[108][109] Other types of wood were still occasionally used, however. The sculpted wood canopy of the Shrob ou Shouf Fountain in Marrakesh was made of palm wood, for example.^[32]: 128 The famous Minbar of the Kutubiyya Mosque, which was fabricated in Cordoba (Spain) before being shipped to Marrakesh, was made primarily of cedar wood but its marquetry decoration was enhanced with more exotic woods of different colors such as jujube and African blackwood.^[83]

A very prominent and distinctive element of Moroccan and Moorish architecture is its heavy use of carved stucco for decoration across walls and ceilings.^[2][4] Stucco, which is relatively cheap and easily sculpted, was carved and painted with motifs from a large repertoire including floral and vegetal motifs (arabesques), geometric patterns, calligraphic compositions, and muqarnas forms.^[4][2] (These were also common features in sculpted wood decoration.)

Tilework, particularly in the form of mosaic tilework called zellij, was a standard decorative element along lower walls and for the paving of floors. It consisted of hand-cut pieces of faience in different colours fitted together to form elaborate geometric motifs, often based on radiating star patterns.^[4][2] Zellij made its appearance in the region during the 10th century and became widespread by the 14th century during the Marinid period.^[4] It may have been inspired or derived from Byzantine mosaics and then adapted by Muslim craftsmen for faience tiles.^[4] The tiles are first fabricated in glazed squares, typically 10 cm per side, then cut by hand into a variety of pre-established shapes (usually memorized by heart) necessary to form the overall pattern.^[3] This pre-established repertoire of shapes combined to generate a variety of complex patterns is also known as the hasba method.^[110] Although the exact patterns vary from case to case, the underlying principles have been constant for centuries and Moroccan craftsmen are still adept at making them today.^[3][110]

Metal, particularly bronze and copper, was also used to decorate or protect certain elements. Notably, the doors of many medieval mosques and madrasas were covered with bronze or copper plating which was carved and chiseled with geometric, arabesque, and calligraphic motifs.^[4] The oldest surviving bronze artworks in Moorish-Moroccan art, for example, are the 12th-century bronze fittings found on several doors of the Qarawiyyin Mosque in Fes.^[29]

Al-Andalus and the western Maghreb, including Morocco, was home to a distinctive style of Islamic architecture.^[111] Often referred to as "Hispano-Moorish"^[3]: 13 or "Hispano-Maghrebi" architecture,^[112] it was characterized by horseshoe arches, cuboid minarets, geometric decoration, vegetal motifs, and muqarnas vaulting.^[111][113] Instead of developing more complex structural designs, it prioritized, from around the 13th century onward, the development of more extensive and dense decoration, notably in carved plaster and mosaic tilework. Decoration was focused on the interior of buildings rather than their exteriors, though exterior gateways and minarets were an exception.^{[113][114][3]: 11} The interiors are typically arranged around central courtyards.^{[113][112][42]}

The most characteristic arch type of western Islamic architecture is the horseshoe arch,^[3]: 15 which became ubiquitous in the region from the early Islamic period.^[2]: 45 Starting in the Almoravid period, the first pointed or "broken" horseshoe arches began to appear and became more widespread during the Almohad period.^[2]: 234 During the same era, the polylobed arch also became part of the common repertoire of arch profiles while the more ornate lambrequin arch also began to appear.^{[2]: 232–234} The use of muqarnas (also known as "stalactite" or "honeycomb" sculpting) developed in the region under the Almoravids and then became a regular feature afterwards, with mosque interiors frequently incorporating several muqarnas vaulted ceilings over specific areas.^[113][111]

In surface decoration, the development of complex geometric motifs was likely encouraged by the trend towards aniconism in Islam. These included designs with curved lines, which were less diverse but widely used in Morocco, and designs with straight lines, which were also common throughout the Islamic world and are often based around a central star-like pattern that branches outward with interlacing lines into a self-repeating pattern.^{[3]: 31–37} Among the more curvilinear motifs was a net-like lozenge motif that was known as sebka or shabka ("net") or, in one of its variations, darj wa ktaf ("step and shoulder").^{[2]: 232 [3]: 32 [81]: 80}

Floral or foliate ornamentation, in the form of arabesques, developed early in the architecture of al-Andalus, during the rule of the Umayyads of Cordoba, and its earliest significant examples in Morocco are in Almoravid architecture. Almohad architecture continued this tradition but focused on larger-scale patterns, while Marinid architecture used dense but highly stylized variations of it, sometimes with a wider overlaying geometric pattern that generated repetition.^{[3]: 30–31}

Many Islamic monuments feature Arabic inscriptions, which could be both informative or largely decorative. These include foundation inscriptions that record the date of their construction and the patron who sponsored it, inscriptions of Qur'anic verses, exhortations of God, or other religiously significant formulas. Arabic calligraphy, as in other parts of the Muslim world, was an art form. Early inscriptions were generally written in the Kufic script, a style where letters were written with straight lines, while from the Marinid period (13th-14th century) onward the cursive Naskh style was more common.^[3]: 38

Morocco also hosts local styles of vernacular architecture in the rural the Atlas Mountains and Saharan regions to the south and east, which are associated with predominantly Amazigh (Berber) populations. While distinctive, these styles are also intermixed with traditional urban Islamic architectural elements,^[7][86] and differ from region to region.^[87]

Structures in these regions are largely made of rammed earth, mudbrick, rough stone, or a mix of these. The most impressive examples are the kasbahs (fortified palaces, also known as tighremt), ksour (fortified villages, also known as igherm), and agadirs (fortified granaries) that dot the countryside. These structures vary in their layout, with some possessing more regular rectangular plans and others having irregular plans adapted to the terrain. The most important fortified structures are marked by their great height and verticality, with tall walls that taper towards the top and are crowned with triangular or horn-like crenellations.^[87]

This architecture notable for the presence of geometric motifs (called lasserift in Amazigh) used to decorate the exterior of rural kasbahs and other prominent homes.^[115] These motifs are emblematic of Amazigh architecture and are found in vernacular Amazigh architecture in other parts of North Africa.^[115][7] This use of geometric motifs in North African Amazigh architecture is believed to have ancient origins: Henri Terrasse believed they had existed since before the first millennium BC due to their widespread precedents in Asia and elsewhere,^[116] while historian Gabriel Camps dates its origins to the presence of Carthaginian culture in the first millennium BC.^[115] Nonetheless, the art of these decorations have evolved and changed over time.^[86]: 39

The motifs typically consist of a combination of circles, rosettes, hexagons, lozenges, chevrons, chequer-boards, and crosses.^[7][115] These structures were built of rammed earth and mudbrick, and so the motifs were traditionally created by building the walls with recesses along their surface or by laying some bricks further back to form recesses.^[86]: 34 Starting in the early 20th century, however, these motifs began to grow more complex and articulated, in part due to the growing links between the oases regions and the urban culture of major cities like Marrakesh. Patterns made of broader elements formed by recessed bricks and alcoves were replaced with narrower, finer motifs made of lines that were carved directly into the wall surfaces.^{[86]: 36–39} Salima Naji, a Moroccan architect and author on Berber architecture, notes that these more linear decorations, although more complex, lack the balance and rigorous composition of older motifs.^[86]: 38

Some local mansions, such as the Telouet Kasbah and the Taourirt Kasbah used by the Glaoui clan, also hosted decoration and craftsmanship more typical of the imperial cities of Morocco and of the broader Islamic architectural styles prevalent there,^[117][118] or in some cases mixed those traditions with local decorative traditions.^[86] Horseshoe arches, widely used in architectural traditions throughout the region, were also widely used in local Amazigh architecture. As the arches served no structural purposes in rammed-earth architecture, their function was mainly decorative, used for doorways, windows, and blind arches or niches.^[7][115]

In addition to the exterior wall motifs, doors and ceilings could were also decorated in larger residences. Two main types of ceilings are attested: wood ceilings and reed ceilings.^[86]: 62 The first type typically consists of wooden panels, whose surfaces were painted with local geometric motifs, Islamic geometric motifs familiar in the major cities, and epigraphic inscriptions. Reed ceilings, which were constructed with wattles of reed stems, could be arranged to form basic two or three-dimensional patterns and then enhanced with red and black paint.^{[86]: 62–69}

Traditional doors, made of wood, were carved and painted with a variety of geometric motifs which were probably influenced by urban Islamic motifs but interpreted by local craftsmen, often with less precision.^{[86]: 44–51} Doors could also be painted or carved with talismanic seals, resembling medallion or amulet-like compositions containing written words and other symbols such as the seal of Solomon, mihrab-like motifs, and representations of the khamsa.^{[86]: 53–59} Salima Naji notes that some of these decorations were intended to have magical properties, but that in some cases the art forms have likely persisted without the magical connotations.^[86]: 57

The following is a summary of the different major types and functions of buildings and architectural complexes found in historic Moroccan architecture.

Mosques are the main place of worship in Islam. Muslims are called to prayer five times a day and participate in prayers together as a community, facing towards the qibla (direction of prayer). Every neighbourhood normally had one or many mosques in order to accommodate the spiritual needs of its residents. Historically, there was a distinction between regular mosques and "Friday mosques" or "grand mosques", which were larger and had a more important status by virtue of being the venue where the khutba (sermon) was delivered on Fridays.^[28] Friday noon prayers were considered more important and were accompanied by preaching, and also had political and social importance as occasions where news and royal decrees were announced, as well as when the current ruler's name was mentioned. In the early Islamic era of Morocco, there was typically only one Friday mosque per city, but over time Friday mosques multiplied until it was common practice to have one in every neighbourhood or district of the city.^[119][105] Mosques could also frequently be accompanied by other facilities which served the community.^[105][35]

Mihrab in the 12th-century Tinmal Mosque

Mosque architecture in Morocco was heavily influenced from the beginning by major well-known mosques in Tunisia and al-Andalus (Muslim Spain and Portugal), two countries from which many Arab and Muslim immigrants to Morocco originated.^[23] The Great Mosque of Kairouan and the Great Mosque of Cordoba, in particular, were models of mosque architecture.^[2][30] Accordingly, most mosques in Morocco have roughly rectangular floor plans and follow the hypostyle format: they consist of a large prayer hall upheld and divided by rows of horseshoe arches running either parallel or perpendicular to the qibla wall (the wall towards which prayers faced). The qibla (direction of prayer) was always symbolized by a decorative niche or alcove in the qibla wall, known as a mihrab.^[3] Next to the mihrab there was usually a symbolic pulpit known as a minbar. The mosque also normally included, close to entrance, a sahn (courtyard) which often had fountains or water basins to assist with ablutions. In early periods this courtyard was relatively minor in proportion to the rest of the mosque, but in later periods it became a progressively larger until it was equal in size to the prayer hall and sometimes larger.^[38][105]

Lastly, mosque buildings were distinguished by their minarets: towers from which the muezzin issues the call to prayer to the surrounding city. (This was historically done by the muezzin climbing to the top and projecting his voice over the rooftops, but nowadays the call is issued over modern megaphones installed on the tower.) Moroccan minarets traditionally have a square shaft and are arranged in two tiers: the main shaft, which makes up most of its height, and a much smaller secondary tower above this which is in turn topped by a finial of copper or brass spheres.^[2][105] Some Moroccan minarets have octagonal shafts, though this is more characteristic of the northern parts of the country.^[4] Inside the main shaft a staircase, and in other cases a ramp, ascends to the top of the minaret.^[2][105]

Medieval Moroccan mosques also frequently followed the "T-type" model established in the Almohad period. In this model the aisle or "nave" between the arches running towards the mihrab (and perpendicular to the qibla wall) was wider than the others, as was also the aisle directly in front of and along the qibla wall (running parallel to the qibla wall); thus forming a T-shaped space in the floor plan of the mosque which was often accentuated by greater decoration (e.g. more elaborate arch shapes around it or decorative cupola ceilings at each end of the "T").^{[105][38][35]}

The whole structure of a mosque was also orientated or aligned with the direction of prayer (qibla), such that mosques were sometimes orientated in a different direction from the rest of the buildings or streets around it.^[120] This geographic alignment, however, varied greatly from period to period. Nowadays it is standard practice across the Muslim world that the direction of prayer is the direction of the shortest distance between oneself and the Kaaba in Mecca. In Morocco, this corresponds to a generally eastern orientation (varying slightly depending on your exact position).^[121] However, in early Islamic periods there were other interpretations of what the qibla should be. In the western Islamic world (the Maghreb and al-Andalus), in particular, early mosques often had a southern orientation, as can be seen in major early mosques like the Great Mosque of Cordoba and the Qarawiyyin Mosque in Fes. This was based on a reported hadith of the Islamic prophet Muhammad which stated that "what is between the east and west is a qibla", as well as on a popular view that mosques should not be aligned towards the Kaaba but rather that they should follow the cardinal orientation of the Kaaba itself (which is a rectangular structure with its own geometric axes), which is in turn aligned according to certain astronomical references (e.g. its minor axis is aligned with the sunrise of the summer solstice).^{[122][121][120]}

Although much reduced today, the Jewish community of Morocco has a long history, resulting in the presence of many synagogues across the country (some of which are defunct and some of which are still functioning). Synagogues had a very different layout from mosques but often shared similar decorative trends as the rest of Moroccan architecture, such as colourful tilework and carved stucco,^[97][123] though later synagogues were built in other styles too. Notable examples of synagogues in Morocco include the Ibn Danan Synagogue in Fes, the Slat al-Azama Synagogue in Marrakesh, or the Beth-El Synagogue in Casablanca, though numerous other examples exist.^[124][125]

The madrasa was an institution which originated in northeastern Iran by the early 11th century and was progressively adopted further west.^[2][3] These establishments provided higher education and served to train Islamic scholars, particularly in Islamic law and jurisprudence (fiqh). The madrasa in the Sunni world was generally antithetical to more "heterodox" religious doctrines, including the doctrine espoused by the Almohad dynasty. As such, it only came to flourish in Morocco in the late 13th century, under the Marinid dynasty which succeeded the Almohads.^[2] To the Marinids, madrasas also played a part in bolstering the political legitimacy of their dynasty. They used this patronage to encourage the loyalty of the country's influential but independent religious elites and also to portray themselves to the general population as protectors and promoters of orthodox Sunni Islam.^[2][31] Finally, madrasas also played an important role in training the scholars and elites who operated the state bureaucracy.^[31]

Madrasas also played a supporting role to major learning institutions like the Qarawiyyin Mosque; in part because, unlike the mosque, they provided accommodations for students who came from outside the city.^{[3]: 137 [1]: 110} Many of these students were poor, seeking sufficient education to gain a higher position in their home towns, and the madrasas provided them with basic necessities such as lodging and bread.^[28]: 463 However, the madrasas were also teaching institutions in their own right and offered their own courses, with some Islamic scholars making their reputation by teaching at certain madrasas.^[1]: 141

Madrasas were generally centered around a main courtyard with a central fountain, off which other rooms could be accessed. Student living quarters were typically distributed on an upper floor around the courtyard. Many madrasas also included a prayer hall with a mihrab, though only the Bou Inania Madrasa of Fes officially functioned as a full mosque and featured its own minaret. In the Marinid era, madrasas also evolved to be lavishly decorated.^[37][2]

Most Muslim graves are traditionally simple and unadorned, but in North Africa the graves of important figures were often covered in a domed structure (or a cupola of often pyramidal shape) called a qubba (also spelled koubba). This was especially characteristic for the tombs of "saints" such as walis and marabouts: individuals who came to be venerated for their strong piety, reputed miracles, or other mystical attributes. Many of these existed within the wider category of Islamic mysticism known as Sufism.

Some of these tombs became the focus of entire religious complexes built around them, known as a zawiya (also spelled zaouia; Arabic: زاوية).^[35][2][126] They typically included a mosque, school, and other charitable facilities.^[2] Such religious establishments were major centers of Moroccan Sufism and grew in power and influence over the centuries, often associated with specific Sufi Brotherhoods or schools of thought.^[35][120] The Saadian dynasty, for example, began as a military force associated with the zawiya and followers of Muhammad al-Jazuli, a major 15th-century Sufi scholar.^[35][38] The Alawis after them also sponsored many zawiyas across the country.^[4][35] Some of the most important examples of zawiyas in Morocco include the Zawiya of Moulay Idris I near Meknes, the Zawiya of his son Moulay Idris II in Fes, and the tombs of the Seven Saints in Marrakesh.^[35][4]

A funduq (also spelled foundouk or fondouk; Arabic: فندق) was a caravanserai or commercial building which served as both an inn for merchants and a warehouse for their goods and merchandise.^[2][3][120] In Morocco some funduqs also housed the workshops of local artisans.^[28] As a result of this function, they also became centers for other commercial activities such as auctions and markets.^[28] They typically consisted of a large central courtyard surrounded by a gallery, around which storage rooms and sleeping quarters were arranged, frequently over multiple floors. Some were relatively simple and plain, while others, like the Funduq al-Najjarin (or Fondouk Nejjarine) in Fes, were quite richly decorated.^[4]

Hammams (Arabic: حمّام) are public bathhouses which were ubiquitous in Muslim cities. Many historic hammams have been preserved in cities like Marrakesh^[127] and especially Fes, partly thanks to their continued use by locals up to the present day.^[67][66] Among the better-known examples of preserved historic hammams in Morocco is the 14th-century Saffarin Hammam in Fes, which has recently undergone restoration and rehabilitation.^{[67][128][129][66]}

Essentially derived from the Roman bathhouse model, hammams normally consisted of four main chambers: a changing room, from which one then moved on to a cold room, a warm room, and a hot room.^{[2]: 215–216, 315–316 [67]} Heat and steam were generated by a hypocaust system which heated the floors. The furnace re-used natural organic materials (such as wood shavings, olive pits, or other organic waste byproducts) by burning them for fuel.^[130] The smoke generated by this furnace helped with heating the floors while excess smoke was evacuated through chimneys. Of the different rooms, only the changing room was heavily decorated with zellij, stucco, or carved wood.^[2]: 316 The cold, warm, and hot rooms were usually vaulted or domed chambers without windows, designed to keep steam from escaping, but partially lit thanks to small holes in the ceiling which could be covered by ceramic or coloured glass.^[2]: 316

As in many Muslim cities, water was provided freely to the public through a number of street fountains, similar to sebils in the former Ottoman Empire. Some fountains were decorated with a canopy of sculpted wood or zellij tilework.^{[2]: 410–413} Fountains were often attached to the outside of mosques, funduqs, and aristocratic mansions.^[28][38] According to Leo Africanus, a traveler and chronicler in the 16th century, there were some 600 fountains in Fes alone.^[28]: 236 Well-known examples in Morocco include the Nejjarine Fountain in Fes, the Shrob ou Shouf Fountain in Marrakesh, and the Mouassine Fountain attached to the mosque of the same name.^[4][38]

Moroccan cities and towns were supplied with water through a number of different mechanisms. As elsewhere, most settlements were built near existing water sources such as rivers and oases. However, further engineering was necessary in order to supplement natural sources and in order to distribute the water across the city directly.

In Fes, for example, this was accomplished via a complex network of canals and channels which captured the waters of the Oued Fes (Fes River) and distributed them across the entire city. These water channels (most of them now hidden under buildings) supplied houses, gardens, fountains, and mosques, powered norias (waterwheels), and sustained certain industries such as the tanneries (e.g. the famous Chouara Tannery).^{[131][106][28]} Waterwheels were also used to lift water from these canals and into aqueducts to bring them even further, such as the enormous noria, with a diameter of 26 meters, built by the Marinids to supply their Royal Gardens to the north of Fes el-Jdid.^[132]

Marrakesh, located in a more arid environment, was supplied in large part by a system of khettaras, an ingenious and complex system by which an underground channel was dug beneath the slopes in the surrounding countryside until it reached the level of the phreatic zone.^[120] This artificial channel was gently sloped to allow water to drain through it, but was sloped less steeply than the natural terrain so that it eventually emerged at the surface. In this way, the khettaras drew water from underground aquifers located on higher ground and brought them to the surface with the use of gravity alone. Once at the surface, the waters ran along canals and were stored in a cistern or water basin, from which they could then be redistributed across the city.^[120] This system was created under the Almoravids (who founded the city) and further developed and maintained by their successors.^[120]

Oases regions in the desertic areas of Morocco also needed to make extensive use of irrigation and artificial water canals to make agriculture possible. Khettara systems were also used to supplement these water sources, especially as surface waters frequently dried up during the summer months. The Tafilalt oasis region, located along the Ziz River valley, is a notable example of this system.^[133][134]

A riad (also transliterated as riyad; Arabic: رياض) is an interior garden found in many Moroccan mansions and palaces. It is normally rectangular and divided into four parts along its central axes, with a fountain at its middle.^[120] Riad gardens probably originated in Persian architecture (where it is also known as chahar bagh) and became a prominent feature in Moorish palaces in Spain (such Madinat al-Zahra, the Aljaferia and the Alhambra).^[120] In Morocco, they became especially widespread in the palaces and mansions of Marrakesh, where the combination of available space and warm climate made them particularly appealing.^[120] The term is nowadays applied in a broader way to traditional Moroccan houses that have been converted into hotels and tourist guesthouses.^[135][136]

Traditional Moroccan houses were typically centered around a courtyard or patio, often surrounded by a gallery, from which other rooms and sections branched off.^[137][120] Courtyard houses have historical antecedents in the houses and villas of the Greco-Roman Mediterranean world and even earlier in the ancient Middle East.^[120] These houses were inward focused: even rich mansions are usually completely unadorned on the outside, with all decoration concentrated on the inside. There were few, if any, large windows on the outside. The entrance, which led to the courtyard, was typically a bent entrance that prevented outsiders in the street from seeing directly inside the house. As with other traditional Moroccan structures, decoration included carved stucco, sculpted and painted wood, and zellij tilework.^[137][120] The central patio/courtyard, known as the wast ad-dar ("middle of the house") was thus the centerpiece of the house. The size and craftsmanship of this interior space was an indication of the status and wealth of its owners, rather than the house's external appearance.^[120]: 54

Today, modern materials have increasingly replaced certain traditional ones during the renovations of old houses. Wooden mashrabiya-type windows have been replaced with iron grilles, and cement is used for walls and pillars instead of brick and rammed earth.^[120]: 63

Sultans and caliphs, as well as the more powerful and wealthy government ministers in the 19th and 20th century, were able to build extensive palaces. The Dar al-Makhzen (meaning roughly "House/Abode of the Government") referred to the royal palace and center of government in a number of cities, such as the Dar al-Makhzen in Fes, Rabat, Tangier, Meknes, or Marrakesh.^[2][4][35] These palaces are still generally off-limit to most visitors today. However, royal palaces generally had a mechouar, a large walled square which acted as a ceremonial space or parade ground at the entrance of the palace. These squares were accessible to the public and formed the public facade of the ruler's abode, sometimes overlooked by monumental and well-decorated gates leading to the palace grounds (e.g. Bab Mansour in Meknes).^[138][35][3] The mechouars of Fes el-Jdid are examples of these, as was the vast square known today as Place el-Hedim in Meknes. The palaces themselves typically consisted of many structures and pavilions arranged around a series of courtyards, pleasure gardens, and riads.^[2][97] This resulted in palace complexes with a sprawling layout; in some cases this was a consequence of multiple phases of construction taking place in different periods. These palaces often also included a number of normally public facilities such as bathhouses and mosques, thus practically making them self-sufficient and self-contained royal cities.^[138][35] Sultans also built additional outlying palaces and pavilions such as the Dar Batha in Fes, as well as vast gardens on the outskirts of their capital city such as the Agdal Gardens in Marrakesh and the former Mosara Garden in Fes.^{[120][28][132]}

In the 19th and early 20th centuries, grand viziers and other high officials of the government were able to accumulate enough power and wealth to build their own private palaces for themselves and their households.^[35] Examples of these include the Bahia Palace of Ba Ahmed (which was later taken over by the sultan), the Dar al Bacha and Dar Si Said in Marrakesh, the Dar Moqri and Dar Glaoui in Fes, and the Dar Mnebbhi in Fes and its counterpart in Marrakesh. Other local warlords and magnates were also sometimes capable of building their own lavish palaces, such as the Palace of Raissouli in Asilah.^[4] The Kasbah of Telouet, also built by the Glaoui clan and only partly preserved today, is another notable example of a 20th-century palace constructed with traditional methods, but located in a rural mountain town.^[139][140]

Defensive city walls were generally built out of rammed earth^[2] and consisted of a wall topped by a walkway for soldiers, reinforced at regular intervals by square bastion towers. These walls were characteristically crowned by merlons shaped like square blocks topped by pyramidal caps. Major examples of such fortifications still stand in Marrakesh, Fes, Rabat, and other cities.^{[120][4][132]} The defensive walls constructed in Muslim al-Andalus also shared this general form, examples of which have survived in Cordoba, Seville, and Granada.^[120]

As in medieval fortifications elsewhere in the world, Moroccan city walls were pierced with a number of gates to grant access in and out of the city. As these were often the weakest points of a defensive wall, they were usually more heavily fortified than the surrounding wall. Most medieval Moroccan gates had a bent entrance: their passage made sharp right-angle turns once or multiple times in order to slow down any attackers.^{[97][141][120]} They ranged from very plain in appearance to highly monumental and ornamental. Many of the most monumental gates still standing today were built in stone during the Almohad period, including Bab Agnaou in Marrakesh and the gate of the Udayas Kasbah in Rabat.^[30][32] As the defensive function of city walls and gates became less relevant in the modern era, gates became more ornamental and symbolic structures, like the Bab Bou Jeloud gate built in Fes in 1913.^[97]

The term Kasbah (Arabic: قَـصَـبَـة, romanized: qaṣabah) in Morocco generally refers to a fortified enclosure, ranging from small garrison forts to vast walled districts which functioned as the citadel and center of government in the city (such as the Kasbah of Marrakesh or the Kasbah of Tangier).^[4][2][30]

A "kasbah" can also refer to various fortresses or fortified mansions in the Atlas Mountains and the desert oases regions of Morocco, which are also called a tighremt in Amazigh.^[7] In these regions, often traditionally Amazigh (Berber) areas, Kasbahs are typically made of rammed earth and mud-brick (or sometimes stone). They typically have a square floor plan with a central courtyard, multiple stories, and square towers or turrets at the corners. They are often decorated with geometric motifs along their upper walls and topped with sawtooth-shaped merlons.^[7][87] The traditional tighremt in the countryside ranges in size from a small fortified farmhouse to a large dominant structure placed on high ground, intended to assert the power of a local ruler or governor.^[115]: 60 Prominent kasbahs of this kind include examples such as the Kasbah Telouet, Kasbah Amridil, Tamnougalt, and Kasbah Taourirt in Ouarzazate.

Agadirs were fortified granaries typically found in the desert, mountain, and oases regions of southern and eastern Morocco. They are one of the architectural types associated in particular with Amazigh architecture in North Africa. These structures typically consist of a solid outer stone wall, sometimes with fortification towers, inside of which are lines of small storage rooms.^[7][87]

The term qsūr or qsars (also commonly spelled ksar or ksour) is used to denote fortified villages in the desert, mountain, and oases regions of Morocco. These complexes are also associated with Amazigh architecture and are known as igherm in Amazigh languages.^[7][115] They are typically surrounded by a defensive wall reinforced with towers, again built out of rammed earth, mud-brick and/or stone. The perimeter wall typically has just one gate, with most public buildings located near this gate.^[87] The core of a qsur or igherm is often a tighremt or kasbah, a "dominant" house that towers over the other houses of the settlement. In some cases, the tighremt started out as an isolated fortified house and then became the nucleus of a growing settlement as new inhabitants built smaller houses around it.^[115]: 60 Aït Benhaddou is one famous example of a preserved qsar settlement, complete with a tall kasbah near its entrance and an agadir up on a hilltop.^[89][142]

A borj (Arabic: برج) generally referred to a single fort, tower, or bastion, such as the Borj Nord in Fes.^[28][97] A sqala (Arabic: سقالة) was another type of bastion, often a seaside fortification with a platform for canons, like the Sqala of Essaouira or that of the Udayas Kasbah in Rabat.^{[143][144][4]} A ribat (Arabic: رِبَـاط) usually referred to a countryside or frontier fortress ostensibly used by warriors fighting waging jihad on the edge of Islamic territory, though it also referred to a type of fortified "monastery" or spiritual retreat for Sufi adherents, not unlike a zawiya.^[2] A notable example, from an architectural point of view, is the Ribat of Tit south of El Jadida, which was originally constructed by one family in the 12th century.^[2] (Also notably, the name of the city of Rabat derives from its original name Ribat al-Fath.^[30])
