Description: Off the southern shore of Okinawa, Japan, under 20 to 100 feet of water lie enigmatic structures that may have been built by some ancient, “lost civilization”. Skeptics say the large, tiered formations are probably natural in origin (which seems crazy looking at the pictures). “Then, in late summer of the following year,” writes Frank Joseph in an article for Atlantis Rising, “another diver in Okinawa waters was shocked to see a massive arch or gateway of huge stone blocks beautifully fitted together in the manner of prehistoric masonry found among the Inca cities on the other side of the Pacific Ocean, in the Andes Mountains of South America.” This seems to confirm that these are manmade ruins. The architecture includes what appear to be paved streets and crossroads, large altar-like formations, staircases leading to broad plazas and processional ways surmounted by pairs of towering features resembling pylons. If it is a sunken city, it is huge.
