6. Yonaguni Monument - Yonaguni, Japan

Submerged off the coast of the Southernmost Ryukyu Island in Japan are a series of stepped flat steps in a structure so angular and flat, it would suggest man-made intervention although debate within scientific communities continue as to whether it is completely natural, is a natural site that has been modified, or is a man-made artifact.

Only discovered in 1987 by divers looking for hammerhead sharks, Supposed to be around 10,000 years old, neither the regional or national governments of Japan consider it to be of cultural or historical importance and so significant research has not been put into dating the structure or why it is under the sea.

7. Las Bolas - Costa Rica

Around 300 stone spheres appear around the nation of Costa Rica located on the Diquís Delta and on Isla del Caño. Thought to be from the now-extinct Diquis culture, the spheres date from around 600AD. The best-known theory for their existence is that they lined the way to houses of chiefs but this is not a certainty by any means.

Ranging in size and weight, there are many local myths about these rocks but none are particularly forthcoming with evidence.

8. Mohenjo-daro - Sindh, Pakistan

The ancient city of Mohen-daro lies in the desert and is one of the world's earliest major urban settlements. Built around 2500 BC, it was only re-discovered in the 1920s.


With signs of city planning, social organization, and a drainage system it was an incredibly advanced city for its time and no one is quite sure why it was abandoned although many point to the decline of the Indus Valley Civilization.

9. Saksaywaman - Cusco, Peru

A citadel just beyond the limits of the capital of the Incan empire, this walled settlement was most likely built to hold up any approaching forces heading for Cusco. What is unique about its construction is that the walls are made of perfectly carved rocks that slot together without the use of mortar.

How such an ancient civilization managed to achieve such a high-level of construction remains up for debate, especially since it was so good that the walls still stand today, over 1000 years after they were put up.

10. Gobekli Tepe - Orencik, Turkey

Dating to around 8BC, the site consists of buildings thought to be sanctuaries and places of worship and stone pillars. Not linked to any of the major religions, the use and relevance of the stone pillars remain unknown and research into the archaeological site remains ongoing.


With only 5% of the site uncovered, the complex remains a mystery to all those looking to reveal its secrets.
