The Baháʼí House of Worship in Wilmette, Illinois (or Chicago Baháʼí Temple), is a Baháʼí temple. It is the second Baháʼí House of Worship constructed and the oldest one still standing. It is one of eight continental temples, constructed to serve all of North America.[2]

The temple was designed by French-Canadian architect Louis Bourgeois (1856–1930), who received design feedback from ʻAbdu'l-Bahá during a 1920 visit to Haifa. To convey the Baháʼí principle of the unity of religion, Bourgeois incorporated a variety of religious architecture and symbols. Although ʻAbdu'l-Bahá participated in a groundbreaking ceremony in 1912 that laid a cornerstone, construction began in earnest in the early 1920s and was significantly delayed by the Great Depression and World War II. Construction resumed in 1947, and the temple was dedicated in a ceremony in 1953.

Baháʼí Houses of Worship are intended to include several social, humanitarian, and educational institutions clustered around the temple, although none have been built to such an extent. The temples are not intended as local meeting places but are open to the public and used as devotional spaces for people of any faith.

History

[edit]

Early plans

[edit]

In 1903, a small group of Baháʼís in downtown Chicago first discussed the idea of a Baháʼí House of Worship in the Chicago area. At the time, the world's first House of Worship was being built in Ashgabat, Russian Turkistan (what is now Turkmenistan).[3] The Ioas family was particularly involved in the first requests.[4] A Baháʼí from Chicago named Corinne Knight True went on pilgrimage to the Ottoman province in the Levant in 1907 to visit ʻAbdu'l-Bahá, then leader of the religion, and tell him of the growing interest in a local house of worship. During Thornton Chase's pilgrimage, he had asked ʻAbdu'l-Bahá about it as well and was directed to work with True as "complete directions" had been given to her.[5] A series of newspaper articles in the fall of 1908 including Chase among a set of women in several newspapers about the aim of the Baháʼís to build it.[6] This interaction led to the next development of a national sense of community: The election of the first national council of the religion, with delegates present from across the US and Canada, in the spring of 1909.[5] Thirty percent of the members elected were women. ʻAbdu'l-Bahá gave his blessing to the project, but recommended that the structure be built away from the Chicago business district, in a more quiet area near Lake Michigan.[7] The Baháʼís considered building the temple in Chicago's Jackson Park or the suburb of Evanston,[8] but eventually settled on Wilmette, Illinois, just north of Evanston. The site chosen for this project was found by True and selected for its proximity to lake Michigan and natural elevation.[9] True began coordinating work and acted as the treasurer of the growing effort[10] and it became a solace to her life in the face of many personal challenges. Subsequently, American Baháʼís came to refer to her as "the mother of the Temple" and she was eventually appointed one of the Hands of the Cause of the religion. The Baháʼí administrative body True initiated by direction of ʻAbdu'l-Bahá, the Baháʼí Temple Unity, began purchasing land and gradually assumed larger responsibilities across communities until it was renamed the National Spiritual Assembly.[11]

Baháʼís from around the world gradually raised funds to pay for the project. For example, French Bahá'ís were noted as contributing even after facing the January 1910 Great Flood of Paris.[12] A Chicago resident named Nettie Tobin, unable to contribute any money, famously donated a discarded piece of limestone from a construction site.[13] This stone became the symbolic cornerstone of the building when ʻAbdu'l-Bahá arrived in Wilmette in 1912 for the ground-breaking ceremony during his journeys to the West.[14] The actual construction of the building did not begin until the 1920s, after Baháʼís agreed to use a design by Louis Bourgeois.[15] The design was seen as a mixture of many different architectural styles.[16]

Construction

[edit]

By 1922, the first part of the building, the Foundation Hall, was mostly finished, and Baháʼís began using it as a meeting place.[17] Progress on construction soon stalled, however, as funds began to dwindle, and residents of Wilmette began expressing displeasure with the construction site. At this point, many strange rumors about the structure began to circulate. Some people believed that the building was used by the Baháʼís to keep a live white whale. Others said that the building was a refueling station for captured German submarines that had been brought to the Great Lakes.[18]

Construction resumed as contributions from Baháʼís began to increase, and in 1930, the George A. Fuller Company was hired to complete the building's superstructure.[19] The superstructure was completed in 1931,[20] and a year later, John Joseph Earley was hired to begin work on the building's concrete cladding.[21] A model of the temple was placed on display at Chicago's 1933–34 Century of Progress Exposition, and people began travelling to Wilmette to see the building taking shape.[22] The temple was featured in a privately issued postal stationery cover on the occasion of the 20th anniversary of US airmail service in 1938.[23] The exterior of the building was completed in January 1943.[24]

Work remained to be done on the interior cladding of the structure, as well as the landscaping around the building. Louis Bourgeois' designs for the interior were incomplete. He had died in 1930, before he could finish his plans,[25] so in 1947, Alfred Shaw was hired to work on the interior detailing of the building.[26] By the 1940s the temple was again featured on a privately issued postal stationery cover[23] and was used by the US Navy during World War II as a rendezvous point for training fighter pilots from the nearby Glenview Naval Air Station, and, by 1946[27] to mark a flightpath of a Navy Mars Seaplane.[28] A plan for the building's gardens was approved in 1951, based on a design by Hilbert E. Dahl.[29]

Dedication and afterwards

[edit]

The temple was finally dedicated on May 2, 1953.[30] Over 3,500 people attended the services,[31] including 91-year-old Corinne True.[32] Rúhíyyih Khánum, the wife of Shoghi Effendi (head of the religion after the death of ʻAbdu'l-Bahá), read a prayer at the dedication.[33] Several prominent figures, such as Supreme Court Justice William O. Douglas and future justice Thurgood Marshall, sent messages of praise to the Baháʼís.[34]

From 1958–2001, the Wilmette Bahá'í House of Worship was associated with a "home for the aged", operated by the U.S. Bahá'í community.[35] The Bahá'í Home has since closed, although the building remains in use for a local Bahá'í School and a regional training center.[36] A new welcome centre for the House of Worship was completed in 2015, described as connecting the temple with the community, including Bahá'ís and non-Bahá'ís.[37]

The House of Worship is a domed structure surrounded by gardens and fountains[38] on a 6.97-acre (2.82 ha) plot of land. The space between the floor of the auditorium and the ceiling of the dome measures 138 feet (42 m) high, and the interior of the dome is 72 feet (22 m) in diameter. The auditorium seats 1,191 people.[39]

Since nine is the last number in the decimal system, Baháʼís believe it symbolizes perfection and completion.[40] Nine is also the value of the word Bahá (Arabic for "glory") in Abjad numerology.[41] Thus, many elements of the building occur in groups of nine. For example, there are nine entrances to the auditorium, nine interior alcoves,[39] nine dome sections,[42] and nine fountains in the garden area.[38]

The cladding of the building is composed of a concrete mixture of portland cement and two types of quartz.[43] Many intricate details are carved into the concrete. Various writings of Baháʼu'lláh, the founder of the religion, are inscribed above the building entrances and inside the interior alcoves.[39] Symbols of many religions, such as the Christian cross, the Star of David, and the star and crescent, can be found in each exterior pillar. The pillars are also decorated with a symbol in the form of a swastika, which is also used by Hindus and Buddhists.[44] At the top of each pillar is a nine-pointed star, symbolizing the Baháʼí Faith.[38]

Inside the center of the dome ceiling, one can see an Arabic inscription. This is a Baháʼí symbol called the "Greatest Name"; the script translates as "O Thou Glory of Glories". The secretary of Shoghi Effendi writing on his behalf explained, "By 'Greatest Name' is meant that Baháʼu'lláh has appeared in God's greatest name, in other words, that he is the supreme Manifestation of God."[45]

Recognition

[edit]

In 1978, the House of Worship was added to the National Register of Historic Places.[1] The building has become a popular destination for tourists,[47] and the Illinois Office of Tourism has named it one of the "Seven Wonders of Illinois".[48] In 2012, the Bahá'í community of the United States celebrated the 100 years of the temple cornerstone dedication.[49] In celebration of the 2018 Illinois Bicentennial, the Bahá'í House of Worship was selected as one of the Illinois 200 Great Places [50] by the American Institute of Architects Illinois component (AIA Illinois) and was recognized by USA Today Travel magazine, as one of AIA Illinois' selections for Illinois 25 Must See Places.[51] In 2019, a photo of the Wilmette Bahá'í House of Worship was among the 15 winners of the annual international Wiki Loves Monuments photo contest.[52]

The Bahá’í House of Worship in , is the oldest surviving temple of the Bahá’í Faith and the only one in , serving as a universal house of worship dedicated to , , and the promotion of unity among all humanity. Located at 100 Linden Avenue along the shore of , the temple is open daily to visitors of all faiths at no charge, attracting over 300,000 people annually for its serene gardens, devotional programs, and architectural beauty. Construction of the temple began in the early 20th century following the Bahá’í Faith's arrival in the United States in the 1890s, with land acquired in Wilmette in 1907 and the cornerstone laid on May 1, 1912, by ‘Abdu’l-Bahá, the son of the Faith's founder, Bahá’u’lláh. The project spanned over five decades, interrupted by two world wars and the Great Depression, and was financed entirely through voluntary contributions from Bahá’ís worldwide. The superstructure was completed in 1931, the exterior in 1943, and the full interior, including a 140-foot-high dome and nine surrounding gardens, was finished in 1953, with the temple opening to the public on May 2 of that year. Designed by French-Canadian architect Louis Bourgeois, a Bahá’í convert, the temple features a distinctive nine-sided form symbolizing the Faith's emphasis on the oneness of God, religion, and humanity, drawing architectural elements from diverse traditions including Eastern, Islamic, Gothic, and styles. Its exterior is constructed from cast concrete panels made with and crushed quartz aggregate, creating a luminous effect often described as the "Temple of Light," while intricate arabesque lacework on the panels allows to filter into the central auditorium. In recognition of its architectural and historical importance, the temple was added to the in 1978 and designated one of Illinois's Seven Wonders. As the "Mother Temple of the West," the Wilmette House of Worship holds profound spiritual significance in the Bahá’í Faith, one of eight continental temples worldwide, embodying principles of , equality, and global unity without or rituals, focusing instead on silent and scriptural readings from all religions. It continues to function as a center for community service, , and , with a new welcome center completed in 2015 and its 30-acre grounds maintained as a public park fostering reflection and harmony.

History

Planning and Site Acquisition

The Baháʼí Faith was introduced to the in 1894, when Thornton Chase, a resident of , became the first American to recognize and embrace its teachings after studying materials sent from Persia. Chase's conversion marked the beginning of organized Baháʼí activities in , centered initially in , where a small community formed around discussions of the Faith's principles of unity and progressive revelation. In 1903, members of the Chicago Baháʼí community petitioned 'Abdu'l-Bahá, the appointed successor to the Faith's founder Bahá'u'lláh, for permission to construct a House of Worship in the region, inspired by the existing temple in 'Ishqábád (now , ). 'Abdu'l-Bahá approved the initiative, emphasizing its role as a of unity for the , and in 1907, Corinne Knight True, a prominent Chicago Baháʼí, traveled to Acre (then in Ottoman ) to present a formal petition on behalf of the community; there, 'Abdu'l-Bahá reaffirmed the need for such a structure in and instructed True to lead the effort. This guidance transformed the project from a local aspiration into a continental endeavor, underscoring the temple's significance as the "Mother Temple of the West." To coordinate the planning and development, the Baháʼí Temple Unity was established on March 20, 1909, during the first Baháʼí National Convention in , serving as a temporary administrative body to manage the temple's construction and related activities. Composed of elected delegates from across the and , the Unity incorporated legally to hold property and oversee finances, marking an early step in the institutionalization of the North American Baháʼí community. Site selection focused on areas near to facilitate accessibility for the growing Baháʼí population, with emphasis on a location symbolizing spiritual outreach toward the continent. In 1907, the initial purchase of two lots comprising approximately 5.5 acres of undeveloped swampland in —along the shore of just north of the city—was completed for $10,000, funded through individual contributions from local Baháʼís. This site was chosen for its proximity to Chicago's urban center, affordability, and evocative position facing the vast waters of , which 'Abdu'l-Bahá later described as a threshold to the spiritual horizons of the . Additional parcels were acquired over the following years to expand the grounds to nearly seven acres by 1914. Fundraising efforts commenced in earnest in 1910 under the direction of the Baháʼí Temple Unity, relying solely on voluntary donations from Baháʼís worldwide in accordance with the Faith's principles. Initial campaigns emphasized small, sacrificial contributions to embody collective unity, and by , significant support arrived from Persian Baháʼís, who, despite facing severe and economic hardship in their homeland, sent substantial sums equivalent to years of labor—often in the form of jewelry or savings—to advance the project as a gesture of with their American coreligionists. These early donations, totaling thousands of dollars by the mid-1910s, laid the financial groundwork for site preparation and future construction, highlighting the global dimension of the endeavor.

Design Development

The design process for the Baháʼí House of Worship in , began formally in 1920 when a nationwide competition solicited submissions from American architects familiar with the faith's principles. Among the 18 entries received, the model crafted by French-Canadian architect Louis Bourgeois stood out for its innovative synthesis of diverse architectural traditions. Bourgeois, who had become a Baháʼí in 1906 and initially proposed a concept in 1909, refined his 1920 model after consulting in , where he received guidance to scale it down while preserving its core vision. Bourgeois's design blended Eastern and Western elements, featuring a nine-sided dome inspired by Russian Orthodox onion domes, Persian motifs, and Indian temple forms to symbolize the of all religions—a central Baháʼí tenet. The nonagonal structure, emblematic of the numeral nine in Baháʼí representing completeness and perfection, underscored principles of , with nine entrances and surrounding gardens intended to welcome all humanity without distinction. Despite some concerns over its structural feasibility raised by engineers, the model was unanimously approved by the delegates to the Baháʼí in April 1920, with Horace Holley, a prominent Baháʼí leader, playing a key role in its advocacy and final selection amid deliberations that extended into 1922. Alternative submissions, including those by Remey, were considered but ultimately rejected for not fully aligning with ʻAbdu'l-Bahá's directives on embodying spiritual harmony through architectural form. To address practicality issues, the superstructure underwent revisions in under engineering oversight, adapting Bourgeois's aesthetic intent for viable construction while maintaining the original's symbolic integrity. These modifications ensured the design's endurance, transforming conceptual ideals into a feasible blueprint for the temple's realization.

Construction Process

The construction of the Baháʼí House of Worship in , began in earnest in 1921, following years of planning and site preparation, with initial work focused on laying the foundation under the guidance of key Baháʼí figures including Corinne True, who played a pivotal role in advancing the project and is often referred to as the "Mother of the Temple." Work progressed to complete a foundation hall by 1922, which served as a temporary meeting space, but was halted shortly thereafter due to unresolved design challenges stemming from Louis Bourgeois's original conceptualization and the lingering economic and material shortages from the . Construction resumed around 1930 when the Company was contracted for the superstructure, though progress remained intermittent as the severely limited funding and resources, confining efforts primarily to preparatory ornamentation and structural assessments. The onset of further exacerbated delays, restricting material availability and labor, yet the project persisted on a reduced scale through global Baháʼí contributions that sustained incremental advancements. The superstructure reached completion in 1931, the exterior ornamentation in 1943, and interior work advanced from 1947, culminating in full completion in 1953 at a total cost of $3,212,517.60, entirely funded by voluntary donations from Baháʼís worldwide without reliance on loans or external financing. Among the engineering challenges was erecting the 140-foot central dome, supported by nine symbolic pillars representing major , which required pioneering methods to achieve the structure's intricate, luminous finish using aggregate for and aesthetic . These techniques, developed by concrete specialist John Earley, involved exposing pebbles in the aggregate to create a textured, light-reflecting surface while ensuring structural integrity against environmental stresses near . The project's supervision fell to architect John Brogan in later phases, ensuring fidelity to the evolving design amid wartime constraints.

Dedication and Early Operations

The in , was formally dedicated through a consecration service for Baháʼís on May 1, 1953, followed by a public dedication on May 2, 1953, conducted by Amatu’l-Bahá Rúḥíyyih Khánum as the representative of , Guardian of the . The events drew over 2,500 Baháʼís from 33 countries for the private service and approximately 3,600 public attendees across multiple sessions on the following day, with an additional 1,500 gathered outside, highlighting the temple's global significance. The ceremonies included choral selections, readings from sacred writings, and the unveiling of a sacred portrait of Bahá’u’lláh, and were amplified through international radio broadcasts via WRUL in reaching , the , and , as well as a short aired on 50 television stations and news distribution to 397 cities worldwide. The dedication capped decades of intermittent construction amid world wars and economic hardships, finally realizing the vision set forth by ‘Abdu’l-Bahá in 1912. Immediately following the public ceremony, the temple opened for its first worship services on May 2, 1953, featuring devotional programs with readings from the holy books of various religions, conducted without or sermons in accordance with Baháʼí principles of unity and simplicity. In the ensuing years, the temple rapidly emerged as a key destination, attracting thousands of visitors annually and serving as a focal point for interfaith reflection and community gatherings. By , the surrounding landscaping—comprising nine gardens, fountains, and approaches designed to symbolize harmony—was completed, enhancing the site's serene environment and supporting its growing role in devotional and educational activities. Early post-dedication developments included the establishment of visitor facilities in to accommodate influxes of pilgrims and the construction of auxiliary structures, such as the Home of Worship in 1957, to expand operational capacity for worship and administrative functions.

Architecture and Features

Structural Design

The Baháʼí House of Worship in Wilmette, Illinois, features a nine-sided polygonal structure symbolizing the unity of all religions and the Baháʼí emphasis on the number nine as representing completeness and perfection. This radial symmetry extends to nine entrances and nine surrounding pillars, each adorned with symbols from major world faiths, such as the cross, Star of David, and Islamic crescent, to evoke the oneness of humanity. The design draws from diverse architectural traditions, incorporating Byzantine dome forms, Gothic ribbing, Romanesque clerestory elements, and Eastern arabesque motifs, creating a harmonious blend that transcends cultural boundaries. At the center rises a prominent dome constructed from panels mounted on a , engineered to ensure structural integrity while allowing for intricate ornamental detailing. The dome, with an interior height of 140 feet and a of approximately 72 feet, caps the , which provides seating for about 1,200 people. This engineering approach, involving with exposed white quartz aggregate, supports the building's overall form without relying on traditional load-bearing walls, contributing to its luminous and ethereal appearance. The integration of light and space forms a core symbolic element, with latticed arabesque panels filtering natural daylight into the interior during the day and emitting a soft glow outward at night, fostering a sense of spiritual elevation and unity. Conceptualized by architect Louis Bourgeois, this design prioritizes openness and accessibility, aligning with Baháʼí principles of collective worship. The structure's foundation spans 204 feet (62 meters) in diameter, encompassing the nine-sided form and radial pathways that enhance its geometric harmony.

Materials and Ornamentation

The Baháʼí House of Worship in , features an exterior constructed primarily from precast and , utilizing mixed with crushed aggregate and quartz to achieve a luminous, marble-like appearance. This exposed aggregate technique, developed by ornamental concrete expert John Earley, exposes larger quartz pebbles on the surface, creating a shimmering effect that reflects light and enhances the structure's ethereal quality. Ornamentation consists of intricate arabesque tracery in a lace-like pattern, drawing inspiration from Islamic mosques and Gothic cathedrals to symbolize the unity of world religions. These decorative elements, including symbolic motifs on the nine exterior pillars, were crafted using elaborate molds applied to the precast concrete panels for efficiency and precision. The panels were produced off-site and assembled on location, allowing for the complex detailing that adorns the temple's nine-sided form. The materials incorporate and silica components, which contribute to exceptional resistance and minimal requirements over decades of exposure to the elements. The predominant color palette evokes purity and spiritual light, with the aggregate providing subtle golden accents through its natural translucency under varying .

Interior Layout

The interior of the Baháʼí House of Worship in , centers on a spacious circular bounded by a nine-sided perimeter, embodying the Baháʼí principle of unity through the symbolic use of the number nine. This design facilitates a space for and , with simple pews arranged in a semi-circular formation around a central raised platform used for readings and choral performances. The accommodates approximately 1,200 seated visitors, allowing for communal gatherings while maintaining an atmosphere of quiet reflection. Rising 140 feet (43 meters) above the floor, the auditorium's dome incorporates clerestory windows that permit diffused to permeate the space, enhancing its serene and ethereal quality. Indirect illumination from the dome's translucent cast-concrete structure, combined with subtle artificial lighting, creates a glowing effect that underscores the temple's designation as a "Temple of Light." The acoustic properties of the dome and auditorium are optimized for choral music and devotional readings, with sound systems integrated seamlessly into the to support clear projection without visual distraction. Furnishings throughout the interior remain minimal and inclusive, devoid of religious icons or altars to emphasize universality. Prominently displayed on the walls are inscriptions from the sacred writings of nine major world religions, positioned above the nine interior alcoves and doorways to symbolize the oneness of faith. Access to the auditorium is provided through nine doors connecting to an adjacent devotional reception area, ensuring smooth flow for visitors entering for personal contemplation or group services.

Grounds and Surroundings

Garden Design

The gardens surrounding the in , were designed by Hilbert Dahl, whose plans were initially developed in 1938 and approved for implementation in 1951, with completion following the temple's dedication in 1953. This expanded the site to encompass approximately 9 acres of manicured grounds, organized into nine nearly circular garden sections that echo the temple's nine-sided form to symbolize completeness and unity in the . The design features formal terraced gardens that step down from the temple's elevated base to the perimeter grade, creating a series of contemplative spaces with central fountains, linear walkways, and borders of evergreens such as columnar junipers. Perennials, shrubs, and annuals fill the beds, with each of the nine gardens showcasing unique plant materials framed by evergreens to provide structure and seasonal interest. The pathways, including a circumambulatory walk encircling the temple, represent spiritual journeys and the principle of , drawing visitors through diverse plantings that evoke harmony among varied elements. Water features are integral to the layout, with nine fountains—one in the center of each garden—symbolizing spiritual purity and renewal in , their gentle sounds enhancing the serene atmosphere while offering views toward to the east. To maintain year-round appeal, the gardens receive meticulous care, including the annual planting of around 20,000 tulip bulbs in the fall alongside other seasonal updates, with hand-pruning of shrubs and trees to preserve the original vision.

Additional Site Elements

The Welcome Center, situated west of the main temple structure along Linden Avenue, functions as the primary hub for visitor orientation and education. Completed in May 2015 following construction that began in August 2012, this 19,000-square-foot facility houses interactive exhibits detailing the temple's history and the principles of the , along with a short introductory and opportunities to engage with volunteer guides. It also features a bookstore offering , scriptures, and related materials, as well as dedicated spaces like the Fireside Room for prayer, meditation, and informal discussions on spiritual topics. The Foundation Hall, an underground auditorium completed in 1922 as the initial phase of the temple's construction, provides a versatile venue for community events, meetings, and gatherings. Located beneath the main worship space, it has served as an essential auxiliary area for Baháʼí activities since its early use, supporting the site's role as a center for reflection and service. Service buildings and administrative offices, developed on the grounds during the 1950s and 1960s in the wake of the temple's 1953 dedication, handle operational needs including maintenance, staff coordination, and visitor support. These structures ensure the smooth functioning of the site as a and public access. Parking facilities and access paths are engineered to support the temple's substantial footfall, with capacity for over 1,000 daily visitors during peak periods, complemented by proximity to public transit like the CTA Purple Line. Accessibility features, such as ramps and designated paths, promote inclusivity for individuals with mobility challenges. In recent decades, the grounds have integrated native plantings and habitat enhancements to foster and local , aligning with the Baháʼí emphasis on while connecting auxiliary elements like pathways to the broader site.
