Les arcs de st-pierre

The Saint-Pierre arches may be evidence of the ebb and flow of the sea that covered the Grands Causses millions of years ago, or they may be ancient witnesses to an underground network that has now collapsed. In any case, these 3 arches still stand on the Causse Méjean in the middle of a forest, in the commune of Saint-Pierre-des-Tripiers. They were rediscovered by Abbé Solanet. This mysterious place is only accessible on foot.

The cave burials

The path leads past a small balsam, the ” grotte de l’Homme Mort” (Dead Man’s Cave ). Excavations carried out in the cave in the 19th century uncovered some 50 human skeletons dating back to the Copper Age, some 35,000 years ago. Most of the skulls found here bore traces of trepanation, as at Baumes Chaudes below the Point Sublime panorama.
