Alconétar Bridge
The Alconétar Bridge (Spanish: Puente de Alconétar), also known as Puente de Mantible, was a Roman segmental arch bridge in the Extremadura region, Spain. The ancient structure, which featured flattened arches with a span-to-rise ratio of 4–5:1, is one of the earliest of its kind. Its design suggests that the bridge was erected in the early 2nd century AD by the emperors Trajan or Hadrian, possibly under the guidance of Apollodorus of Damascus, the most famous architect of the time.
The almost 300 m long Alconétar Bridge served as a crossing point for the Roman Via de la Plata, the most important north–south connection in western Hispania, over the Tagus, the longest river of the Iberian Peninsula. It presumably remained in service until the Reconquista, after which numerous early modern reconstruction attempts by Spanish engineers failed. The ruins, which were mainly to be found on the right river bank, were relocated from their original position in 1970 when the Alcántara reservoir was created.
The historic Alconétar Bridge, which should not be confused with the monumental Alcántara Bridge further downstream, spanned the Tagus not far from the mouth of the Almonte, in the heart of the Spanish Cáceres Province in the Extremadura region. A modern motorway and a railway, which cross the Tagus in the immediate vicinity, underline the historical importance of this crossing point between northern and southern Spain. During the building of the Alcántara Dam in 1970, the remains of the bridge were moved from their original site to a meadow six kilometers to the north, close to the municipality of Garrovillas de Alconétar. By contrast, few traces are left of the neighbouring ancient bridge over the river Almonte.
In the classical period, the Alconétar Bridge was part of the Roman road Iter ab Emerita Caesaraugustam, that was later called Via de la Plata. This important inner Iberian connection led from the provincial capital Mérida in the south, through the river valleys of Alagón, Tiétar and Tagus to the north, then on to the western part of Meseta Central, passing the major town of Salamanca. Its terminal point was Astorga in north-western Spain. The Via de la Plata was one of the four main routes which were established by Augustus (30 BC–14 AD) and his successors for military control of the peninsula and for facilitating the exploitation of the rich Spanish silver and gold mines.
Apart from the junction over the Tagus, the remains of four other ancient bridges can be found along the road: one over the Albarregas, another over the Aljucén, a third close to Caparra and a fourth over the Tormes. In the hills overlooking the Alconétar Bridge, a Roman mansio with the name of Turmulus (Spanish: "Ad Túrmulos") was established, according to the then customary distance intervals. It was the fourth of a total number of sixteen between Mérida and Astorga.
The exact construction date of the Puente de Alconétar is unknown because of missing literary and epigraphic sources. Its segmental arches suggest that it was built in the early 2nd century AD, more specifically during the reign of the emperors Trajan (98–117 AD) or Hadrian (117–138 AD), as the use of this arch form was typical of that era. Both rulers were born in the southern Spanish province of Baetica and Trajan is known to have ordered the restoration of the Iter ab Emerita Caesaraugustam when he came to power. Segmental arches were often employed by Trajan's court architect Apollodorus of Damascus, such as in Trajan's Forum and most notably in the greatest civil engineering achievement of its time, Trajan's Bridge, which rested on twenty huge concrete piers and was used during the Dacian Wars for moving troops across the more than 1,000 m (3,300 ft) wide Danube.
Moorish geographers make no mention of the Alconétar Bridge, even though they praise the Roman bridge of Alcántara which also leads across the Tagus. There is some evidence that a community called Alconétar, Alconétara or Alcontra (Arabic: "small bridge") existed at least temporarily – probably an indirect reference to the high-rising bridge of Alcántara. It also remains unknown why the bridge of Alconétar is called Puente de Mantible in the local vernacular, an expression which alludes to the legend of Charlemagne and his Twelve Paladins.
The bridge was probably in use until the time of the Reconquista, when the Tagus constituted the border between the Christian and the Moorish realm from the 11th to the 13th century, and the frequent clashes might have easily made the ancient bridge unusable. According to another theory, the water could have begun to wash away the ancient foundations at the time.
