Franck Goddio, an underwater archaeologist, shares the explorations of three recently re-discovered cities off the coast of Egypt, including Alexandria (1997 NOVA documentary *), Canopus, and Thonis-Heracleion (the Egyptian and Greek names for the city, not to be confused with the ancient Egyptian city of Tanis). A new documentary on Thonis-Heracleaion was produced for the Franco-German TV network, Arte, and you can watch the German version here. [more inside]
In 1628, the Swedish man-o-war Vasa sank to the bottom of the Baltic Sea moments into her maiden voyage. 333 years later this remarkably well-preserved ship was resurrected from her ocean grave and brought to drydock.
A sunken megalithic city, perhaps 6,000 years old, has been sonar-photographed with an underwater sub, off the coast of Cuba, 2100 feet down. Well, at least they didn't describe it as 'cyclopean'. Nor is there any word on whether its architectural angles are non-Euclidean. [More inside]
The Ancient Underwater Pyramids of Japan. "A STRUCTURE thought to be the world's oldest building, nearly twice the age of the great pyramids of Egypt, has been discovered. The rectangular stone ziggurat under the sea off the coast of Japan could be the first evidence of a previously unknown Stone Age civilisation, say archeologists. The monument is 600ft wide and 90ft high and has been dated to at least 8000BC. The oldest pyramid in Egypt, the Step Pyramid at Saqqara, was constructed more than 5,000 years later."
