Torre de Valdés Salas is a medieval 14th-century tower in Salas, Asturias, forming part of a fortified complex connected to the adjoining Valdés Salas palace via an arcaded bridge displaying heraldic shields. The square tower features four floors, barrel vaults, and a narrow spiral staircase, with its cellar once serving as a dungeon. Declared a Cultural Heritage Site, it now houses the pre-Romanesque Museum of San Martín de Salas and is historically significant as the residence of Fernando de Valdés Salas, the Major Inquisitor of Spain, founder of the University of Oviedo, and Archbishop of Seville.
