Castle of Trigueros del Valle Monument · Trigueros del Valle, Campiña del Pisuerga, Valladolid It was built in the 15th century by the Robles family, with two walled enclosures of which stables, towers and the main gate survive, the gate bearing the date 1453 carved on its lintel. In 1427 John II granted Fernán Alfonso de Robles the privilege of founding an entailed estate with the town of Trigueros and its valley, though he was imprisoned that same year and executed three years later for betraying the constable Álvaro de Luna. The lordship was inherited by his son Gutierre de Robles, who together with his wife María de Guevara carried out the main works on the castle, whose coats of arms appear over the gate next to the carved date. The lords' despotism led to the townspeople's assault on the castle on 16 January 1521, during the anti-seigneurial revolt of the War of the Comunidades, an episode re-enacted every summer.
