Castillo de Huelma is a 15th-century quadrangular fortress rising above the white-walled village of Huelma in Jaén province, Andalusia. Originally a strategic al-Andalus village-fortress during border conflicts between Castile and Granada, the castle was captured for Castile in 1438 by Íñigo López de Mendoza, 1st Marquis of Santillana. Built utilizing advanced artillery techniques of its era, the castle features four cylindrical towers equipped with quadruple loophole rows and crossfire loopholes for defensive firepower. Declared a Bien de Interés Cultural in 1985, it remains an important monument to medieval military engineering.
