History.
The castle dates back to the 12th century when king Ferdinand II of León built a watchtower on a site overlooking the river Tormes. King Sancho IV of Castile converted the tower into a castle, which destroyed in the times of king Henry IV of Castile. The House of Alba took possession of the site and García Álvarez de Toledo, 1st Duke of Alba rebuilt the castle as fortress and private residence. Fernando Álvarez de Toledo, 3rd Duke of Alba turned the castle in a true renaissance palace. Where the sober exterior contrasted with the rich interior containing beautiful frescos depicting the Battle of Mühlberg, where the duke distinguished himself. During the Napoleonic Wars the castle was destroyed, only one tower remained, which is still owned by the Alba family.
Archaeological excavations were made to uncover the former splendour of the castle-palace in 1991
