A team of researchers say they might have found the lost city of Atlantis, which is thought to have been destroyed by a tsunami thousands of years ago. They believe its ruins could be buried under mud flats in southern Spain, just north of Cadiz. Using deep-ground radar, digital mapping and underwater technology to survey the site, archaeologists and geologists believe they found the city buried in the marshlands of Dona Ana Park. Head researcher Richard Freund, a professor at the University of Hartford, Connecticut, found a series of “memorial cities” built in Atlantis’ image by refugees after its likely destruction, which convinced researchers it could very well be the real thing. Accounts from Greek philosopher Plato, written 2,600 years ago, were used to help them pinpoint it. The region is notorious for its tsunamis, although debate about whether Atlantis really existed has gone on for thousands of years.
