Castle of Sádaba Monument · Sádaba, Cinco Villas, Zaragoza The castle of Sádaba stands at the top of a small rocky hill east of the town, in the comarca of the Cinco Villas, rising some fifteen metres above the rest of the town, next to the river Riguel. The area was resettled in the 11th century, and around 1125 Alfonso I the Battler raised a fortress more primitive than the current one, of which the so-called King's Tower survives, next to the access gate. The castle preserved today, rectangular in plan with circular towers, was already built in the 13th century: around 1223 Fernando de Leret is documented as tenant in what was called Sádaba Nueva, the moment at which it is believed the present fortification was raised, in the midst of the dispute between Aragon and Navarre over control of the town, placed in 1215 under the protection of the Navarrese king Sancho VII the Strong.
