The Concentric Rings or other architectural features extracted by artists from Plato’s description of the capital of Atlantis have 
continually fascinated students of the story and many have attempted to link them with similar ancient features found elsewhere in the world as evidence of a widespread culture. Stonehenge, Old Owstrey, Carthage and Syracuse have all been suggested, but such comparisons have never been convincing. Diaz-Montexano has recently published(a) a fragment of pottery found near Seville in Spain that shows concentric circles and insists that it is a symbol of Atlantis. Ulf Erlingsson has made a similar claim regarding some concentric circles carved on a stone basin found at Newgrange in Ireland.
Two papers presented to the 2005 Atlantis conference on Melos describe how an asteroid impact could produce similar concentric rings, which if located close to a coast could be converted to a series of canals for seagoing vessels. The authors, Filippos Tsikalas, V.V. Shuvavlov and Stavros Papamarinopoulos gave examples of such multi-ringed concentric morphology resulting from asteroid impacts. Not only does their suggestion provide a rational explanation for the shape of the canals but would also explain the apparent over-engineering of those waterways.
At the same conference the late Ulf Richter presented his idea, which also suggests that the concentric rings around the centre of the Atlantis capital had a natural origin. Richter has proposed that the Atlantis rings were the result of the erosion of an elevated salt dome that had exposed alternating rings of hard and soft rock that could be adapted to provide the waterways described by Plato.
Georgeos Diaz-Montexano has suggested that the ancient city under modern Jaen in Andalusia, Spain had a concentric layout similar to Plato’s description of Atlantis.
Gigal Rafaim
Perhaps of equal interest is the 5,000- year-old site of Gilgal Refaim, on the Golan Heights, currently occupied by Israel. It is remarkably similar to Plato’s description of the capital of Atlantis and could be easily claimed as a model of that city, perhaps with greater legitimacy than many of the other suggestions(a).
