The Carlist general Ramón Cabrera ordered the castle destroyed, during the First Carlist War (1833-1840), before leaving the town so that it would not serve as a fortification for the liberal troops. Of the medieval enclosure only remains are left on the hill of Santa Bárbara, which dominates the houses from the north. 1839 Photo: Willtron (Wikimedia Commons) (CC BY-SA 3.0) What to see and do in La Fresneda
