The castle was built in the 15th century as a castle-palace by the fourth Count of Benavente, Don Rodrigo Alonso Pimentel, a member of the powerful Castilian nobility and the owner of many castles.
The structure has a regular, square ground floor. The multi-storey Tower of Homage, commonly known as "Macho", is protected by a drawbridge. The castle is surrounded by a wall protected by semi-cylindrical cubes. On the eastern flank there are many windows and a large balcony. The only piece of ornamentation is a coat of arms on a ledge.
It was recently restored and turned into a
Municipal Library and Cultural House.
