You can meet at the "Place du Champ de Foire" of Nozay to begin this historical trail. Step by step, you will discover the history of the shale, this characteristic local rock has been a huge part of Nozay’s landscape. It has been sculpted to pave the Roman roads, then to build manors, barns, calvaries, churches or wash houses and ovens…, the blue slate is everywhere.
On your way, do not hesitate to open the doors of "L’Enclos", an ancient churchyard of medieval architecture made in shale, ranked as a historic monument.
Then, you can walk along the variant of "Les Grées" (no access with horses), that has an interpretive trail in which you will go in an ancient blue slate quarry transformed into a sports natural area (rock-climbing, mountain bike and orienteering).
