Discover the Blue Mine

50 km northwest of Angers, in the Segréen region, La Mine Bleue is located in the heart of a former slate quarrying site, at Noyant-la-Gravoyère.
An emblematic roof covering of the Anjou region, blue slate blends with the white of tuffeau in the Loire Valley to create the typical contrast found on all Loire castles.
While the old tuffeau quarries have been rehabilitated as mushroom beds or wine cellars, the slate quarrying sites were often abandoned. The Galetière slate quarries in Noyant have been converted into a tourist site: its purpose is to convey the work of the miners who extracted the slate there from 1916 to 1936.
You can discover the depths of the mines and the surprising schist scenery, as well as the miners' difficult working conditions.
You'll also learn about the physical characteristics of slate and its uses, from extraction to cutting, in building, art and everyday life. Take advantage of your stay in Angers to discover the region's natural heritage on walks along the beaten track. Hikers will appreciate a guided tour of this magnificent site, and can enjoy an open-air picnic as they leave the mine.

Take time to visit the blue mine from the Ponts de Cé campsite in Angers.

Dive 126 meters underground

The exceptional nature of the Mine Bleue site lies in the depth to which visitors are invited to descend: 126 metres below ground at the lowest point of the visit! It's an impressive descent, aided today by an elevator, but one that miners used to make on foot, via an 830-step staircase.
