Saint Michel mound near Carnac (Brittany, France), built between 5,000 and 3,500 B.C. It is a Neolithic burial monument consisting of an artificial hill, 120 meters in length and 60 meters wide. In the funerary chamber grave goods have been discovered, which are now in the Musée de préhistoire (Prehistory Museum) in Carnac. In the XVIIth century on the top of the mound was built a chapel dedicated to Saint Michel. The complex testify of the continuity in the holiness of the place and shows how the Christian worship tended to substitute the ancient cult of the dead, though in popular religion prominent traces of it have been left.
