According to legend, a wagon and its entire team fell inside. The horses and coachman died, smashing against the stone. Some believe that the ghost of the unfortunate man has been haunting this cursed excavation ever since, and that it's possible to glimpse him after dark...

Undoubtedly one of the most breathtaking places in Revin, but one of the most difficult to reach. It's best to have strong legs. The Godin Hole (the name is uncertain), several centuries old, originated from a prospecting operation in the rock face. It lies at the bend of a small, steep path overlooking the house in the middle of Fallières. "It comes from the search for slate schists. At the time, people were very poor and looked for slate by digging into the rock. There are other similar holes along the stream below, they extend all the way to the Plateau," says Edmond Szelong, a history buff. No one knows exactly when this breakthrough was made, probably in the 18th century. The imposing cavity, dug into this porous rock, inexorably lets water seep through. It fills with every downpour. “Children used to be responsible for emptying it every morning using buckets.”

The Trou des Saracens is a karst cave formed several million years ago. Used since the Neolithic era, this site served as a refuge and habitat. The waters deposited stones containing iron ore, called “Sarrazin” by the local inhabitants, supplying the Virelles forges until the 18th century. Today, the cave is protected for its archaeological and ecological value, particularly for the hibernation of bats.
