The Alcántara Bridge (Puente de Alcántara) is a historic Roman arch bridge in Toledo, Spain, spanning the Tagus River. Its name derives from the Arabic "al-qanţarah," meaning "the arch." Originally constructed by the Romans to provide access to the city, the bridge has undergone several reconstructions due to damage from wars and natural disasters. Notably, during the Middle Ages, it served as a primary entrance for pilgrims into Toledo.
The Alcántara Bridge features two main arches and is flanked by fortified towers. The western tower, adorned with the coat of arms of the Catholic Monarchs, was reconstructed during the reign of Alfonso X after suffering flood damage. The eastern tower was replaced by a Baroque triumphal arch in 1721 due to its deteriorating condition. The bridge's strategic importance made it a focal point during various historical conflicts, leading to multiple repairs and restorations over the centuries.
