Carnac

The Carnac stones (Breton: Steudadoù Karnag) are an exceptionally dense collection of megalithic sites in Brittany in northwestern France, consisting of stone alignments (rows), dolmens (stone tombs), tumuli (burial mounds) and single menhirs (standing stones). More than 3,000 prehistoric standing stones were hewn from local granite and erected by the pre-Celtic people of Brittany, and form the largest such collection in the world.
