Torreón de Navardún is a substantial 13th-century Gothic fortress standing 26 meters tall in the Cinco Villas region of Zaragoza, near the historic kingdom boundary between Aragón and Navarra. Constructed of stone in a rectangular floor plan, the tower served as a key defensive structure in a once-larger fortified compound protecting against medieval Muslim threats. The name itself reflects the fortress's ancient heritage, combining pre-European elements (Navar) with Celtic (dún, meaning city or fortress), indicating continuous occupation and strategic importance over more than a thousand years. Originally an episcopal palace built over earlier Navarrese kingdom defenses, the tower has undergone comprehensive restoration and now houses an interpretation center exploring the complex history of Aragonese-Navarrese frontier politics, representing the finest Gothic-era tower architecture in the region.
