Castle of Torrelobatón Monument · Torrelobatón, Montes Torozos, Valladolid The castle of Torrelobatón, also known as the castle of the Comuneros, stands on the Montes Torozos and is one of the best preserved in Castile and León; it was declared a Historic Heritage site in 1949. It was begun in the 13th century to watch over the Hornija valley and belonged to the Enríquez family, admirals of Castile, whose coats of arms adorn the keep; it was completed in the mid-15th century thanks to Gómez de Isla, who worked on Palencia cathedral, following the model of the Valladolid school. The keep is about forty metres high by twenty on each side, with five-metre-thick walls and a staircase of 143 steps. In February 1521 it was the scene of a victory by the comuneros after an eight-day siege, and the last place where they left their mark before being defeated at Villalar.
