Castillo de Magaña rises dramatically on a steep hillside in Soria province, dominating the Alhama River valley with a distinctive double-enclosure design rare in 15th-century Spanish architecture. This important stately castle combines Berber-origin masonry elements with later medieval renovations, featuring a square inner keep with corner towers and a lower outer enclosure with seven strategically placed towers. Built in the 15th century and once granted to the powerful courtier Álvaro de Luna, the castle's preservation condition exceeds most comparable fortresses of its era. The structure showcases masterful medieval military design adapted to mountainous terrain.
