Located on an island in the ancient archipelago of Corocondamitis, between the Black Sea and the Palus Maeotis, Phanagoria covered an area of 75 hectares (190 acres) of which one third has been submerged by the sea.Before the underwater city was discovered, the notion of Phanagoria as a city was just another story in mythology. Fiction became real when archaeologists unearthed a gravestone of the legendary Hypsikrates, the wife of Mithradates VI. This underwater city now lies under the waters of the Black Sea, but long ago it was the largest Greek city. Further explorations were made and divers saw marble plinths, artifacts, and that amazing tombstone.
Shi Cheng, Chun'an County, Zhejiang, China. An ancient city, established about 1300 years ago, now lies at the 26-40 m depth underwater. In 1959, the city was deliberately flooded to make way for a hydro-electric project and the Xin’an dam. More than 300,000 residents, who had lived there for generations, were evacuated to create the artificial Qiandao Lake. The man-made lake covers an area of 573 square km (221 square mile) and has been remarkably well-preserved 85 to 131 feet under the lake, depending on one’s location. The ancient stone buildings with their Chinese inscriptions stand intact along the main avenues and streets just like it did almost sixty years ago. Even the wooden beams and staircases are intact. The water actually protects the various components of the city from the sun, wind and rain.
