Château de Quéribus is a well-preserved medieval castle, or "citadel of vertigo," situated on a rocky outcrop 728 meters high in the Corbières mountains of southern France. It served as the last bastion of the Cathar resistance during the Albigensian Crusade, a refuge for heretics fleeing persecution. Strategically positioned on the border with Aragon, it functioned as a key French royal fortress until the border shifted in 1659. Visitors today can explore its defensive features, including three rings of walls, a keep, and a remarkable Gothic Pillar Room, and enjoy breathtaking panoramic views of the surrounding landscape.
