Castillo de Cambil occupies an entire rocky plateau west of the town of Cambil on a nearly vertical cliff face above the Cambil River, exemplifying medieval mountain fortress design. Built in the 12th century or earlier as part of the Nasrid Kingdom's border defenses established in 1246, this strategic stronghold required a historic siege by 6,000 Jaén troops using artillery to finally conquer it in 1485—marking one of the Iberian peninsula's earliest uses of artillery warfare. With natural defenses on three sides and only its western approach requiring fortification, this Bien de Interés Cultural now offers exclusive panoramic views across Sierra Sur de Jaén from approximately 600 meters elevation.
