Located on an old Muslim fortress reconquered in 1085 under the reign of Alfonso VI. The first testimonies of the castle come from the hand of Alfonso VII, who gave the properties to the dukes of Mendoza. These, in the s. XV, they would build a castle fortified by seven different towers, built with brick in the Mudejar style. The Marquis of Santillana and, later, Juana de Portugal and her daughter, Juana la Beltraneja, would reside there. During the War of Independence, the French would use the fortress as a barracks, fleeing from it in 1813, destroying it in their escape, then beginning its deterioration. It currently has a bullring inside and has been closed for restoration since 2016. It is a historical gem that should not be overlooked if you visit the Madrid town.
