CASTILLO DE PORTILLO (R)
Considered one of the first fortifications of the Valladolid school of the fifteenth century, built at a time of weakness of the monarchy before the power of the nobles, on an earlier castle of the fourteenth century. It has a square floor plan with the homage tower at an angle and three doors defended by cubes, which surrounds the courtyard. The entire building was surrounded at the end of the fifteenth century by a barbican with cubes in the corners and moat, now disappeared. After passing through several owners in the last 200 years, the castle has now become the property of the University of Valladolid. It is partially restored and can be visited.
