Château de Montségur

About this place

The Château de Montségur is a former fortress near Montségur, a commune in the Ariège department in southern France. Its ruins are the site of a razed stronghold of the Cathars. The present fortress on the site, though described as one of the "Cathar castles," is actually of a later period. It has been listed as a monument historique by the French Ministry of Culture since 1862. In July 2026, the Royal Capetian Fortresses of Languedoc were designated by UNESCO as a World Heritage Site. Look at the entrances, walls and surrounding terrain together. Their relationship helps explain how the site controlled movement and protected its occupants, while later alterations can reveal the shift from military stronghold to residence or monument.
