The fortress was annexed by the French crown in 1229, following the defeat of the Cathars.
The Saint-Jordi keep is situated on the highest point of the ridge, reachable via a steep, narrow stone staircase.
In 1258, the Treaty of Corbeil solidified the castle's role as a primary defensive post on the French-Aragon border.
The castle is built directly into the natural geological fissures of the limestone rock, which form part of the internal defensive walls.
The site was abandoned as a military installation in 1659 following the Treaty of the Pyrenees, which moved the border further south.
Excavations have revealed that the site was utilized for human habitation as early as the prehistoric era.
The masonry incorporates 'opus spicatum' (herringbone) patterns typical of early medieval construction in the region.
Château de Peyrepertuse is a sprawling ruined fortress built along a limestone ridge 800 meters above sea level in the Corbières Massif. It functioned as a strategic Cathar stronghold and later a French royal garrison defending the former border with the Kingdom of Aragon. The site consists of three distinct sections: the lower enclosure, the central keep, and the Saint-Jordi keep connected by the 'Escalier Saint-Louis' carved directly into the rock. Its massive curtain walls are largely intact, spanning a length of 300 meters across the precipitous ridge. The architecture features Romanesque vaulted chapels and defensive crenellations dating from the 11th to 13th centuries. It is one of the 'Five Sons of Carcassonne,' a group of fortresses fortified by the French monarchy following the Albigensian Crusade. The site is characterized by significant vertical exposure, with sheer drops on both sides of the limestone cliff.

Wear hiking boots with high-traction soles as the limestone paths are uneven, steep, and slippery when wet.
Bring windproof outer layers, as wind speeds on the ridge are frequently intense even on calm days.
Ensure you carry sufficient water, as there are no amenities for purchase once you begin the ascent from the base.
Attempting the climb during high wind alerts or thunderstorms, which occur frequently due to the extreme elevation.
Closed on December 25th and January 1st; may close temporarily during extreme weather conditions such as high winds or ice.
Strictly remain on marked paths to avoid high-risk cliff edges; no climbing on ruin walls.
