Castillo de Hornachuelos is a fortress of Hispano-Muslim origin in the municipality of Hornachuelos, Córdoba province, built during the 8th-9th century Emirate period and modified during the Caliphate of Córdoba. The fortress formed part of a defensive system protecting the Guadalquivir valley population and controlling regional access. In 1240, Ferdinand III the Saint besieged it during his Andalusian conquest, achieving surrender by cutting off the water supply through mountain-fed pipes. Following Granada's conquest in 1492, the fortress lost its defensive necessity. Today, the impressive Tower of Homage remains standing with two superimposed dome-covered chambers, along with the arms plaza, cistern, and partial walls, though extensively damaged.
