60 Most Mysterious Places On The Earth That You Should Visit

Yonaguni Monument

Yonaguni is located deep down in Japan’s southern island chain in the vicinity to Taiwan. Previously this island was renowned for hammerhead sharks but the whole focus shifted when in 1987, one diver came across an amazing yet confusing thing. He had found Yonaguni Monument. The structure is built with a slew of sandstone and mudstone and the point to note is that the way that the structure is constructed does not look to be built by mother nature. Notably, the biggest construction is some 130 feet wide, 90 feet tall, and 500 feet long.
