Frías Castle

history of the castle dates back to the first fortresses of the tenth century. Located on a rock overlooking the Tobalina Valley, it is one of the most spectacular rock castles in Castile, having a great strategic value. It would begin to have more importance when it passed into the hands of King Alfonso VIII in 1201, giving it strategic value, since it would relieve the castle of Petralata of the functions of control of the territory, built by the Navarrese in 1040 to defend the most important passes between La Bureba and Castilla la Vieja.
