Castillo de Sádaba is a 13th-century Cistercian-Gothic fortress located in the Five Towns region of Zaragoza. Built during the reign of Sancho VII the Strong of Navarre, the structure served as a strategic military outpost near the border of the Kingdoms of Navarre and Aragon. The castle features a distinct rectangular floor plan protected by seven towers of varying heights and defensive shapes. It is constructed entirely of ashlar stone, showcasing superior masonry typical of the period. Unlike many residential castles, this site was designed primarily for defensive garrison duty. The central courtyard is surrounded by a high curtain wall that still largely retains its original silhouette. The structure was declared a Bien de Interés Cultural in 2006, recognizing its architectural and historical value to the Aragon region.
