Discovery of an underground historical site to trace part of Nancy’s history.

The visit is quite athletic (good physical condition necessary) and rather aquatic. Two options to choose from:

• Simple visit: Lasting from 1h30 to 2h, it consists of the descent of the well of Clairlieu (38 m) equipped every 3 m of bearings connected by fixed ladders, followed by a round trip in the gallery. The presence of water and the spacing of the ladder bars limit the age of the visitors. From 10 years.
• Crossing: Lasting about 3h, it consists of the descent of the well of the Virgin (63 m) using caving techniques, followed by the route of the artificial underground river for about 2.7 km to go up through the well of Clairlieu (38 m) using fixed scales. From the age of 12.
