Castillo de Unzueta, Medieval rock castle in Zeberio and Orozko, Spain
Castillo de Unzueta is a medieval rock castle situated on a mountain between Zeberio and Orozko at about 766 meters (2,500 feet) elevation. The ruins consist of stone foundations and wall sections, though the mountaintop has been altered by a modern communication tower.
The castle was built between the 11th and 12th centuries as part of Navarre's defensive network. It was destroyed in 1358, likely during the regional conflicts of that period.
The site shows traces of how people lived in the Middle Ages, with water storage systems and pottery fragments still visible. Visitors can see how residents managed daily activities in this remote mountain location.
Reaching the castle involves hiking up very steep slopes that require proper footwear and physical effort. Be prepared for a challenging climb and check weather conditions beforehand, as the paths become slippery when wet.
The castle could see directly to nearby Malvecin Castle, and together they formed a strategic defensive line controlling entry routes into the region. This shared visual connection allowed defenders to spot approaching threats from considerable distance.
