Secrets of the Great Wall

So enormous, it is the only manmade object that can clearly be seen from outer space. So old, its secrets have only now been discovered through this unprecedented collaboration between Chinese agencies, NASA, and the Discovery Channel film team.

The Great Wall stands as an unequaled testament to mankind’s ability to achieve the seemingly impossible. Three thousand years of history lie buried in the battlements and ruins that stretch for an estimated 4,500 miles roughly the same distance as Miami to the North Pole!
