Brittany in northwestern France is sometimes referred to as Little or Lesser Britain. It 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.2019 saw a report that “Bettina Schulz Paulsson, an archaeologist at the University of Gothenburg, reexamined some 2,410 radiocarbon dating results that have been assigned to Europe’s megaliths and put them through a Bayesian statistical analysis. Based on the picture the data present, Schulz Paulsson believes that the megaliths were first constructed by dwellers of northwest France during the second half of the fifth millennium BC.” (b) Mike Parker Pearson, Stonehenge’s leading, authority, has endorsed this idea of a French origin for megalith building(c).
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 saw 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.

Britain as the home of Atlantis has been claimed by many writers and not without undertones of nationalism by some of the British authors. Nevertheless, support for the idea has been offered by a number of the more disinterested researchers. Probably the first to advance this idea was John Wallis in 1700, who proposed that the Atlantis story had been corrupted over time and was a reference to the destruction of the landbridge that had existed between France and England, leaving a British Atlantis more isolated (The original Brexit!). It was nearly a century later that the idea was taken up by Thomas Pennant. More than another century passed before Cooper, Spence, Beaumont and Calestani produced related theories. Fast forward to the 21st century, when Donald Ingram identifies the Wessex II culture as Atlantean and Melville Nicholls considers Britain to be one of the Atlantean islands referred to by Plato.
The precise location, the exact date and the probable cause of the destruction of Atlantis are the basis for a range of theories. There is general acceptance that following the deglaciation at the end of the last Ice Age vast regions of low-lying land that had linked Ireland and Britain to mainland Europe were gradually flooded.
One school of thought is that these flooded regions contained Atlantis, of which the most extensive was in the North Sea and is now known as Doggerland. Other offshore locations proposed for Atlantis are the Celtic Shelf (Gidon, Steuerwald & Koudroiavtsev) and the Irish Sea (Dunbavin). These lands had been settled and following the inundations its inhabitants forced to retreat to the higher ground of what is modern Europe and the British Isles.
>David L. Hildebrandt in Atlantis-The Reawakening  proposes a reworking of the ‘Atlantis in Britain’ theory with some new perspectives. For me, his dating, location and identity of the Atlanteans does not ring true, particularly why Stone Age people in Southern Britain would want to launch an attack on Athens, over 2,000 miles away, a city-state which did not even exist at the time. Those early Britons did not have the wheel, yet Plato tells us that the Atlanteans had chariots!<
E. J. de Meester on his now defunct website postulated a link between Stonehenge and Atlantis(b). After arbitrarily dividing Plato’s dimensions by ten, he suggested that the plain described by Plato lay in a rectangle between Salisbury and Chichester.
Professor François Gidon, a French botanist, proposed over seventy years ago the existence of a Bronze Age Atlantis on the Celtic Shelf near Britain. He dated this inundation to between 3,000 and 1,200 BC. However, this date is too late as the area had already been submerged for some thousands of years during an event known as the Flanders Transgression, which began around 7,000 BC. A further problem with his theory is that since Atlantis, according to Plato, contained mountains, the submersion of the relatively shallow Celtic Shelf would at least have left their peaks still visible, a feature missing from the Celtic Shelf.
