Megaliths Around the World

Pidan is one of the most famous mountains in Siberia. There are no road to it, and it takes about 5-6 hours on foot to get there along paths. It is 4374 feet tall. Tales tell of a flying woman around the mountain who was supposedly witnessed by Japanese reporters and even filmed for Japanese television. It is filled with stone walls and megaliths that are ancient.

Construction began on Tiwanaku, an Inca city, in Bolivia around 700 AD. 

Carnac Stones in France were erected between 4500 to 2000 BC. They are found in a circular formation.
