Where is the Great Wall?

Over two thousand years ago, with his land under constant attack from nomads, the First Emperor of China came up with a simple solution: build a wall to keep out enemies. But its construction came at a huge cost: it is believed that more than a million Chinese died building it, earning the wall its nickname the longest cemetery on earth. The story of the Wall tells the story of China itself the rise and fall of dynasties, the greatness of its culture, and its present-day status as Communist world power.
