Ancient Underwater City

In the waters around Okinawa and beyond to the small island of Yonaguni, divers located eight separate locations beginning in March 1995. That first sighting was equivocal - a provocative, squared structure, so encrusted with coral that its manmade identity was uncertain.
Then, as recently as the summer of 1996, a sports diver accidentally discovered a huge, angular platform about 40 feet below the surface, off the southwestern shore of Okinawa. The feature's artificial provenance was beyond question.
Widening their search, teams of more divers found another, different monument nearby. Then another, and another. They beheld long streets, grand boulevards, majestic staircases, magnificent archways, enormous blocks of perfectly cut and fitted stone - all harmoniously welded together in a linear architecture unlike anything they had ever seen before.
