Pierre du Bigot

This pink granite block measures about 2 meters long and 1.5 meters high with roughly 46 cup marks carved into its flat surface. The boulder has naturally rounded edges from being moved by ice age glaciers.

An archaeologist discovered this prehistoric stone in 1911 and shared the findings with the French Prehistoric Society. The discovery showed that this area had been inhabited since early Neolithic times.

The cup marks on the stone come from the Neolithic period and show that early people lived in this area. These markings suggest ritual or practical activities took place thousands of years ago.

The stone sits on private land in the Bigot hamlet on Mûrier Hill and can be reached by walking paths. Using marked trails and respecting private property makes for a better visit.

The stone is partly made of micaschist, a material that stands out from typical pink granite found nearby. This unusual composition makes it a distinctive geological example in the area.
