Based on astonishing new archaeological finds and extraordinary first-person accounts, this film tells the story of one of the greatest wonders the world has ever known: The Great Wall of China .

It is more than 3,000 miles long and was built in just 20 years by a workforce of nearly 50,000, who used technology and construction techniques that inspire awe even today. The engineering triumph came at colossal cost and would eventually hasten the end of the Ming dynasty.
