Castillo de Alcaraz rises on Cerro de San Cristóbal at 1,030 meters elevation, overlooking the Albacete town of Alcaraz in Castilla-La Mancha. Built during the 10th and 11th centuries in the Caliphate period, this strategic fortress became crucial following King Alfonso VIII's 1213 conquest, serving as Castile's gateway toward Granada, Murcia, and the Levantine territories. The castle played a pivotal medieval role controlling rivalries between Castile, Granada, and local lordships throughout the Reconquest. Razed by the town's residents in 1475 after the Catholic Monarchs besieged the stronghold, the ruins now rest on private property, preserving its medieval silhouette against the southern Spanish landscape.
