The 8 Royal Fortresses of Languedoc UNESCO World Heritage

The 8 Royal Fortresses of Languedoc — UNESCO World Heritage

Since 26 July 2026, the "Capetian Royal Fortresses of Languedoc" have been officially inscribed on the UNESCO World Heritage List. This exceptional network of eight sites — seven in the Aude and one in the Ariège — bears witness to the power of 13th-century Capetian military architecture, built after the Albigensian Crusade to secure the new border of the Kingdom of France against Aragon.

• Comtal Castle – City of Carcassonne: the heart of the defensive system. Double ramparts, fifty-two towers, and the largest still-inhabited fortified medieval city in Europe.

• The Four Castles of Lastours: four castles aligned along a single rocky ridge north of Carcassonne.

• Château de Termes: destroyed on Richelieu's orders in 1653; its ruins still overlook the Termenès gorges.

• Château de Puilaurens: one of the best-preserved, with an imposing keep.

• Château de Quéribus: the last Cathar stronghold, fallen in 1255, with its circular keep.

• Château de Peyrepertuse: the largest site, with an upper and lower castle stretching along a 300-metre ridge.

• Château d'Aguilar: the most isolated, amid the vineyards of Tuchan.

• Château de Montségur (Ariège): the most symbolically charged site, the last Cathar refuge before the 1244 siege.
