The Nocé de Pierres, at the foot of Mont-Saint-Michel de Brasparts is a megalithic alignment comprising an alignment approximately 300 m long of 77 small menhirs oriented east-west and about ten menhirs according to secant orientations.
The menhirs are made of Armorican sandstone dating from the Ordovician and the location is at the limit of two watersheds, that of Éllez in the north and that of Douffine in the south.
