Located on a strategic rocky hill that dominates the Esponne valley, absolutely unattackable on three sides -only vulnerable on the northwest-, it is a castle that dates back to 1034, where Catharism was absolutely rooted. From that moment until the Crusade, it was owned by the Lords of Pailhés (who were at all times on the side of the Count of Toulouse and Foix). In 1273, after the imprisonment of the Count of Foix, the castle passed into the hands of the crown. In the 17th century, Richelieu ordered the total destruction and demolition of the castle and the town, to erase all traces of the Cathar church and its believers. It was completely destroyed by the inhabitants of the surrounding area, led by the Count of Foix. It is currently in ruins.
