Scene of the final crusade against the Cathars, the Château de Montségur, perched on its rocky crag 1,216m above sea level, occupies a site towering above a series of cliffs. It commands an exceptional view of the Plantaurel hills, the Aude Valley and St-Barthélemy Range. In 1244, the castle surrendered its arms and 207 Cathar martyrs who had taken refuge there were burned at the stake. You can still make out the plan of the fortress which hugs the surface of the summit.
