Historic village located at the crossroads of ancient communication routes, the village of Fenouillet culminates at 530 meters on a rocky spur.
This geographical location gives it a strategic position, with notably the Château Saint-Pierre already in place before 800, seat of a Vicomté, successively dependent on the Counts of Toulouse, Barcelona or the Kings of Aragon. Two lines of fortifications protected the village, defended by two secondary castles: Castel Fizel and Sabarda.
Fenouillet retains traces of the castle, a rare example of seigniorial military architecture that was not altered after the crusade against the Cathars. Archaeological campaigns have enabled a major enhancement of this heritage.
