Underwater pyramids in 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 civilization, 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..
Yonaguni Island is located in western Japan. Yonaguni became famous in the mid 80-x, when divers discovered the mysterious underwater rock terraces and pyramids with sharp corners. Until now, there is debate, but nobody knows what secrets are fraught with the island. Scientists are inclined to believe that these pyramids were created artificially many years ago an unknown civilization that vanished from the face of the earth.
