Armorica was the Latin name given by the Romans to what we know today as the Brittany peninsula. The region contains some of the most remarkable monuments created by the megalith builders, such as those found at Carnac and Morbihan,
Plato described the influence of Atlantis reaching as far as Italy and Libya (Tim. 25b). In Europe megalithic structures have been found extending all along the Atlantic seaboard and into the Mediterranean as far east as Italy(a) and all across North Africa including modern Libya and Egypt, it was understandable when some commentators concluded that these megalithic monuments were a cultural expression of the Atlanteans. The evidence available indicates that the spread of megalithic building was effected by a maritime based society. How much of this spread was brought about through military or trade expansion or just migration is not known.
A number of French and German researchers have identified Brittany as the power centre of the Atlantean ‘confederation’, while the American writer Hank Harrison is working on a book in which he will nominate Morbihan as a possible capital of Atlantis. R. Cedric Leonard has also written an interesting article(b) on the megalithic monuments of Brittany.
While megaliths are also found in the Middle East and across Asia as far as Japan, their greatest concentration is in Western Europe with a suggested focal point in Armorica. The legendary sunken city of Ys, often associated with Atlantis, is reputedly located off the coast of Armorica.
