Castillo de A Peroxa, situated in Ourense's Val do Miño region, represents a rare surviving fortress from Galicia's turbulent medieval period. Built during the 12th century atop an ancient castro settlement, this polygonal fortification was fortified with four semicircular towers, including a central Tower of Homage, and served as the seat of the state of Temes. Remarkably, A Peroxa survived the devastating Irmandiña Revolt of the 15th century that destroyed many regional castles, and later passed to the powerful Sarmiento family as descendants of the Lords of Ribadavia. Designated a Heritage Asset of Cultural Interest since 1994, the castle's surviving structures and strategic positioning over the Miño River tributaries make it an invaluable window into Galician feudal history.
