Castillo de Luna is a fortress constructed in Almohad and Mudéjar style in Mairena del Alcor, Seville, standing strategically on the Alcor ridge between the walled towns of Alcalá de Guadaíra and Carmona, serving as a defensive gateway to Seville. Built in the mid-14th century with four distinctive square towers named la Ruida, la Mocha, la Campanilla, and la del Duque, the fortress features an arms courtyard, outer ramparts, and approximately twenty artillery ports from the 15th century. The castle received its name from the marriage between Don Pedro Ponce de León and the daughter of Don Álvaro de Luna. Since 1902, English archaeologist Jorge Bonsor's restoration work preserved the structure as a museum housing archaeological collections, archives, and artistic pieces reflecting centuries of Andalusian history.
