Granadilla Castle originates from the 9th century and was rebuilt after Reconquista in the 12th century. The current castle was recreated by Don García Álvarez de Toledo in 1473-1478.
Today Granadilla is a ghost town. In 1955, during the Franco regime, its residents had to leave when the Council of Ministers ordered a reservoir to be built nearby. Currently, the area is a summer campsite for young people and tourists.
