Castillo de Píñar occupies a large fortified enclosure on a 932-meter hill in Granada province, likely built during the mid-14th century Nasrid period as a crucial border bastion between Christian Castile and Muslim Granada. This fortress spans nearly 3,000 square meters with an oval base and walls featuring rectangular towers plus two semicircular designs. Inside the enclosure remain ruins of two cisterns, including one with two naves separated by arches and barrel vaults. The castle's last Muslim governor, Sidi Mandri, abandoned it in 1484 to found Tetuán in Morocco, establishing a sister city relationship that endures today. Declared a National Monument, the castle stands in ruin.
