A Chinese city, left to ruin after a dam flooded the valley it lay in, has become a paradise for divers, after an ingenious idea from a local tourist official. The ancient city of Shi Cheng, known as the Lion City because it was surrounded by the five Lion Mountains, was founded over 1,300 years ago, but it vanished more than half a century ago to make way for a man made lake and the Xin'an River Dam Project which houses a hydroelectric power station. 300,000 people had to be relocated. Called the Atlantis of the east, the once bustling city is now between 80 and 131 feet underwater in parts. An Artist's take on what the city would've looked like. The city still stands in almost pristine condition. Many of its buildings, temples, homes, staircases and streets are still intact.
