"Lost stones of Iseki"
Could this be the remains of a long-lost civilisation? We'll let you decide!
Discovered in 1987, these strange rock formations - with clean, geometric lines and smooth, flat surfaces - lie on the ocean floor off the coast of Yonaguni Island. If the rocks are indeed man-made, not simply a result of erosion, they would pre-date the pyramids. Either way this site makes for a fascinating dive.
