Vallon de Tourne and the Mithras bas-relief

Two springs at the foot of a rock, a wash house and a Roman bas-relief of the god Mithras carved into the rock face: a small valley south of the old town.

What to see, what to know

South of the old town, the Vallon de Tourne is a cool, fresh corner. Two resurgent springs emerge from the rock here: the Goul de la Tannerie, or small goul, and the Goul du Pont, or large goul. Their water feeds a wash house at the entrance to the site.

Between the two springs, look at the rock face. A bas-relief shows the god Mithras sacrificing the bull, surrounded by the dog, the snake, the scorpion and the raven. Dating from the 3rd century, it formed the back wall of a temple. It is the only known relief of Mithras in France carved directly into the rock. It has been listed as a historic monument since 1927.

The gouls are also well known to cave divers, who explore a very deep flooded network here. The visit is a walk, in the open air.
