There is no real indication that the so-called "Lost City of Atlantis" actually ever existed as the origins for the myth surrounding the fictional city can be traced back to the writings of the Greek philosopher Plato, who wrote about a continent called Atlantis in 360 B.C. Although there is no real proof that Atlantis ever existed, there have been numerous reports of researchers or explorers supposedly finding the site of the lost city, and there are some scholars who believe that the city was real. For example, in 2011, Phillip Reeder, a professor at the University of South Florida, announced that he found what he believed to be the former site of Atlantis in Spain's Donana National Park.
Although Professor Reeder's announcement came about as the result of academic study and careful exploration, there is no real way to prove that the site he found is that of the city that Plato described. Reeder's find came about as the result of research conducted based on "clues" found in Plato's description of Atlantis. According to the original texts, Atlantis was destroyed by natural disasters, including earthquakes and floods, that resulted in the city being "swallowed up by the earth."
