When was the great wall of china built

The Great Wall of China was built over 2,000 years ago, by Qin Shi Huangdi, the first emperor of China during the Qin (Ch'in) Dynasty (221 B.C - 206 B.C.). In Chinese the wall is called "Wan-Li Qang-Qeng" which means 10,000-Li Long Wall (10,000 Li = about 5,000 km).

The answer is 221-206 B.C. So that means it was built 2,000 years ago.

The peasant farmers did most of the work
