Called "Mont Tombe" in the time of the Celts, this rocky hill was thought by the Benedict monks as a place of worship. Symbol of the French resistance in the war of a hundred years, the mountain was fortified and ended serving as a prison. With time and after a great restoration, it became a World Heritage Site. Today, in its interior you can find its beautiful Abbey that crowns it and a few houses at its feet. It is estimated that only 40 people live permanently (one quarter being monks).
Extremely touristy of course, but extremely amazing as well. We haven't had the chance to see it surrounded by je high tide. Have you?
