Castillo de Nogalte is a 12th-century fortress perched above Puerto Lumbreras in Murcia, Spain, originally constructed by the Moors and later expanded by Christian forces during the Reconquista. The castle commands strategic views over tributaries and historic routes leading toward Granada, Almería, and Lorca. Featuring defensive walls, towers, and panoramic vistas of the surrounding landscape, the site includes restored cave dwellings that reveal insights into regional medieval life. Now freely accessible during daytime hours, the castle offers visitors a well-preserved example of medieval military architecture and serves as a cultural landmark in southeastern Spain.
