The Alcantara Bridge was part of the defensive enclosure of the city of Toledo.
The Alcantara bridge (from the Arabic al-qanţaratu, «bridge») rises over the Tagus River, in the Spanish city of Toledo.
Of presumably Roman origin, it was cited as early as 788 and was built as a confluence of roads that seek the passage to the city from the east, crossing the Tagus River.
It currently has two arches, located at the foot of the castle of San Servando and next to the Puerta de Alcantara, there is evidence of its construction in Roman times, at the foundation of Toletum. It was badly damaged and rebuilt in the 10th century. It is when the third arch disappears, reduced to a porthole with a horseshoe arch. It was one of the bridges that gave entry to the city and in the Middle Ages it was a mandatory entry for all pilgrims.
Under the reign of Alfonso X it suffered serious damage and was rebuilt. The western tower belongs to this last period, later modified and decorated under the reign of the Catholic Monarchs, whose arms decorate its walls.
It was declared a national monument in 1921.
