CASTILLO DE OCIO (R)
Located in a magnificent strategic location, on the border line between Navarra and Castile, initially built in the early medieval period at a point occupied by the Romans, its first historical references are from the 13th century as one of the rebellious fortresses against Sancho IV of Castile. Impregnable on three of the four sides, the current fortress consists of a tower, a one-storey annex building and four concentric wall lines built at various times between the 11th and 15th centuries. At the beginning of this century, two restoration and enhancement campaigns have been carried out.
