An ancient city, called Thonis by the Egyptians and Heracleion by the Greeks, and thought for centuries to be a myth, is currently being excavated and some breathtaking pictures are coming out. The city was mentioned by Herodotus in his writings, and was also said to be a stop on Paris and Helen's war-triggering romp around the Mediterranean, but it was only found to be real in 2000, when it was rediscovered by French underwater archaeologist Dr. Franck Goddio after four years of surveying.
Thonis-Heracleion lies 30 feet beneath the surface of the Mediterranean, near the city of Alexandria, and no one knows yet exactly how it sank—one theory suggests that the buildings may simply have been too heavy for the water-logged soil.
However, the seawater has left the city remarkably well-preserved, and researchers have even discovered Athenian weights in the site, which have never been found in an Egyptian dig before. You can read more about Thonis-Heracleion here!
