CASTILLO DE SÁDABA (R)
Founded by Alfonso I the Battler in 1125 on a previous Arab castle, it was greatly modified in 1215 after its conquest by Sancho the Fort of Navarre. Its floor plan is an almost perfect rectangle, measuring 33 x 25m, of which seven majestic towers stand out, two of which form the access in turn to the interior of the enclosure. In its interior there is a small chapel in the form of a cube, which on the outside is only recognized by two large semicolumns attached to the right of a simple cover.
