Brittany in northwestern France is one of the most exciting regions of Megalithic Europe. The stone rows of Carnac are unequalled, Le Grand Menhir Brisé was once the largest standing stone in Europe, while Morbihan contains a huge number of dolmens and standing stones.
The earliest suggestion that Atlantis may have been the connected with the Armorican peninsula came from François Gidon in the 1930’s when he proposed that Atlantis had been situated on an exposed Celtic Shelf stretching from Brittany to Ireland. Unfortunately, he dates the submergence of this land to between 3000 and 1200 BC, which was millennia after that part of the Celtic Shelf had been inundated by the Flandrian Transgression.
Jean Markle was convinced that the Carnac stone were connected with Atlantis. Recently, Sylvain Tristan followed the work of Jean Deruelle in supporting a megalithic Atlantis. Further support has come from Alfred deGrazia and Helmut Tributsch who sees Megalithic Europe as Atlantis with the island of Gavrinis in Brittany as its capital.
The American researcher, Hank Harrison, considers the Morbihan départment as a significant Atlantean location if not the home of its capital.
