The Puente de Alcántara is a Roman arch bridge in Toledo, Spain, spanning the River Tagus. The word Alcántara comes from Arabic القنطرة, which means "arch".
Located at the foot of the Castillo de San Servando, it was built by the Romans after they founded the city. In the Middle Ages it was one of the few entrances for pilgrims into the city.
It currently has two arches. There is evidence of its construction in Roman times, at the founding of Toletum. It was damaged and rebuilt in the 10th century, at which time a third arch disappeared, reduced to a gate with a horseshoe arch. It was one of the only bridges that gave access to the city and in the Middle Ages it was the obligatory entry for all pilgrims.
