High above the left bank of the river, opposite the Alcántara bridge, is the 11th-century Castillo de San Servando.
The castle was built in the 14th century as a monastery, commissioned by Alfonso VI but also served military purposes because of its strategic location. The building is an exceptional example of a Mudéjar-style fortress in Spain.
With its formidable towers, crenellated defense walls, and Arabic-style entrance gateway, the castle has an imposing presence. This monument is not open to the public. Tourists can only visit the exterior and the grounds.
