The Tower of the Villa de Salas or Torre de los Valdés is a medieval Spanish tower from the 14th century.
The Tower forms jointly with the neighboring Palace of Valdés Salas to which it is connected by a bridge with arcade in which the shields of the Valdés Salas family are located.
The tower is made of carved stonework, with a square floor, with a basement (used in its day as a dungeon), and three floors with a barrel vault joined by a spiral staircase. The roof is crenellated and in its corners there are four cubes. Only three windows open in the Torre de los Valdés, being the rest of vain saeteras flared, of defensive mission, like the matacán of the second floor that being on the entrance door protects the access to the tower, which it was done by a drawbridge over an old moat.
Inside the Tower is the San Martín Pre-Romanesque Museum, which preserves the valuable set of epigraphic pieces and tombstones from the Church of San Martín de Salas, which are an excellent example of the pre-Romanesque decorative wealth of the 10th century.
