About the venue

3 boulevard des Essarts, 54600 Villers-lès-Nancy
  • Site archéologique

The Nancy Speledrome is the former groundwater drainage gallery of the Hague Forest Plateau, built in the early 1900s to supply the city of Nancy with drinking water. With its gradual drying-up, its operation was abandoned in the 1930s. In a century, nature took over its rights and created superb deposits of white calcite transforming the gallery into an exceptional cave at the very gates of the ducal city.
