An exceptional site due to its location. One thing intrigues me: how did the ancients build with stone at such heights? Even on the backs of mules, the task of climbing the 500m drop from the Tarn is gigantic. Other questions: how did they live there? Certainly no prayers.

Far away from all civilization, this hermitage was built on rocks.

The name "Montagne de Trois Croix" already hinted at it, and so it's no real surprise to find more than just a summit cross up here, which – as is common in many places – crowns the mountain peak. The central cross, standing in the middle, points the observer to the execution of the incarnate Son of God, Jesus of Nazareth. According to biblical tradition, however, he was not condemned to death and crucified alone, but together with two criminals. Pope Francis, who died on Easter Monday, once composed the following prayer on this subject: "Help us, Son of Man, to free ourselves from the arrogance of the thief, the robber on your left, and of the short-sighted and the corrupt (...) Instead, we ask you, Son of God, to identify us with the good thief who looked at you with eyes full of shame, repentance, and hope; who, with the eyes of faith, saw divine victory in your apparent defeat and thus knelt before your mercy and grace and stole paradise with honesty and integrity.

The massive structure rising above the landscape at this location – with its round dome (although only the vaulting ribs of the roof dome were built, the actual roof covering was never completed) and the lantern erected above it – and crowned by a cross, doesn't seem to quite fit with the small sacred monument at its peak. User 'Cx' has already provided information in his post about the history of the building and the originally planned statue of the Madonna, which was supposed to bestow its blessing upon the land and its people from here.

A geological curiosity, nice to see. If you're not passing too far, it's worth a little detour.
