After his travel to the tomb of Jesus, in the 6th century, . When he arrived at the forest of Chaumont-Porcien (which no longer exists), he saw the "Bald Mount", called like this because there were no trees on it, whereas the forest covered all the rest of the landscape. Berthauld became Saint-Berthauld, because he spread the God's word in a pagan area. After his dead, an abbey was built. Destroyed many times, there is nothing left.
