Château de Montségur is a 13th-century fortress ruin perched at an altitude of 1,207 meters on a limestone outcrop known as the Pog. It served as the final stronghold for the Cathars, a persecuted religious sect, until its fall to royal forces in 1244. The current site remains characterized by its defensive walls and the remnants of a castrum, or village, which once surrounded the main keep. It is a key site in the history of the Albigensian Crusade. The ruins are accessed via a steep, unpaved hiking trail that begins at the base of the rock. Visitors can observe the architectural remains of the citadel, which was rebuilt in the 13th century after the original fortifications were destroyed. The site provides panoramic views of the Ariège Pyrenees region. Archaeological excavations have identified the layout of the medieval village and various artisan workshops that existed within the perimeter.
