An incredible viewpoint for only 1.4 €
It houses an exhibition on the village of San Vicente de la Barquera, but for me the best part of the visit were the views from the top of the tower (you get an amazing overview of the Puente de la Maza). One of the most beautiful images of the Castillo del Rey is from Puente de Tras or Puente Nuevo, near the castle.
