Ermitage Saint-Pierre de La Roque-Sainte-Marguerite, Medieval hermitage in La Roque-Sainte-Marguerite, France.

Ermitage Saint-Pierre is a pre-Romanesque chapel built against a high dolomite cliff above the Dourbie valley, on a rocky spur below the Larzac plateau rim. The cliff face shows rectangular niches and recesses along a ledge, with a low wall of fitted stones in front of one opening and a masonry structure with vertical supports embedded below.

The chapel was built on a dolomite cliff of the Causse du Larzac above the Dourbie, probably as the castle chapel of Revel. It is first mentioned in 1150, and its pre-Romanesque architecture dates it to the 9th or 10th century. A 1327 act records a bequest of oil for its lamp; after that it was abandoned, and the site was rediscovered in the 1930s by Albert Carrière and Jean Birebent.

The chapel shows features of religious architecture with a triumphal arch dividing the choir from the nave. This design reflects how medieval builders understood the layout of sacred spaces.

Access is on foot by trails from the village of Pierrefiche du Larzac; no road reaches the chapel. The rock spur is steep and the path narrow, so wear walking shoes and watch your footing. The site is exposed on the cliff face, so check the weather before setting out.

The chapel was rediscovered in the 1930s by Albert Carrière and Jean Birebent, and archive research later identified it as the chapel of Revel Castle. In the 19th century, people from Pierrefiche and La Roque-Sainte-Marguerite came here to pray for rain or for healing of eye diseases.
