Oldest Submerged City Visualized With CGI 84
Stirling Newberry writes "Nottingham University's Pavlopetri project spent months measuring a city that sank beneath the waves 3,000 years ago, perhaps in a tsunami. The result is a BBC documentary that features a detailed CGI reconstruction. 'The entire city – covering 20 acres – has been surveyed in ultra-high definition, with error margins of less than three centimeters. ... [T]he survey team has so far located scores of buildings, half a dozen major streets and even religious shrines and tombs.' eScience News chimes in about the oldest known submerged city, first inhabited 5,000 years ago and rediscovered in 1967. Of course, Slashdot readers will probably want to dig into the details of how stereo-vision mapping was used (PDF) to create the map in the first place."

Maybe I'm wrong, but ISTM that a tsunami would only submerge a city temporarily. To stay under for 3000 years you need rising sea, sinking ground, or perhaps a sea breaking into a previously dry area below sea level.

People used to think the same thing about Troy. Then some German guy found it in the late 1800s.
Of course, the real Troy wasn't nearly as large as what Homer's story would have you believe, and there's no evidence of involvement by deities, but the city is real. Similarly, Atlantis, if it exists at all, probably doesn't have any advanced technology like flying machines and the like, but there could very well be a real city somewhere that used to be called Atlantis. After all, this currently unnamed city was once above sea level, and then some earthquakes happened causing the land to subside, and the city sunk; people back then probably assumed it was "the work of the gods".

A submerged city would have be covered with sediment, coral and fauna. A 1970's archeological survey map simplified for audiences would consist of some black squiggly lines superimposed over a blurry underwater photograph, providing conclusive proof that the structure was man-made.
