Hidden From The World: These Are The Biggest Abandoned Places On Earth

One Of The Largest Man Made Holes

This is The Navel of the Earth, one of the largest man-made holes in the entire world. This place may look empty and ugly now, but there was a time when it was known for the production of diamonds. It produced such expensive diamonds that could make any person rich beyond their wildest dreams.

The Mir Diamond Mine (also called Mirny Mine) in Mirny, Eastern Siberia, Russia, is more than 525 meters deep. Due to harsher working conditions and other issues, the mine was closed in 2004.
