Castillo de Luque occupies a vast fortified complex of 36 hectares encompassing not only military installations but an entire defended villa perched on cliffs at the foot of the town. Originating in the final years of the Umayyad Emirate (9th century) on the site of an ancient Roman fortress, the castle was briefly held by rebel leader Ibn Mastana before Ferdinand III's Christian reconquest in 1241. The surviving structure preserves two towers, defensive walls, a massive keep with interior divisions, an Almohad tower from the 12th century, and a 17th-century building. Modern visitors can explore the fortress using audio guides and informational panels.
