On its rocky peak, the castle of Foix and its imposing stature, dominate the medieval town. With a strategic position at the confluence of the Arget and Ariège rivers, the Ariège castle had a strategic role: to control access to the Haute Ariège valley, to monitor the low country and to protect the counts behind its high impregnable walls. It is the symbol of the power of a fiercely independent county engaged in the defense of the Cathar cause. Resisting many assaults, the castle of Foix was never conquered. During the Catholic Church's crusade against Cathar heresy, the counts of Foix, souls of the Occitan resistance, welcomed and protected the persecuted by refusing to submit to the authority of the King of France. It is the cradle of the famous counts of Foix: Gaston Fébus (1331-1391) and Henry III, King of Navarre, future King of France Henry IV.

The former abbey church of Saint Volusien is a single-nave building from the 12th and 13th centuries. It was severely damaged during the Huguenot Wars between 1562 and 1598 and subsequently rebuilt in the High Classical style.
