The '''Great Wall of China''' is any of several extended frontier fortifications in northern China. These were constructed in ancient times as barriers against invading armies. The original wall was built in 220–206 BC by [[Qin Shi Huang]], the emperor who unified China. In modern times, this wall is no longer recognizable from the the ground, but it has been mapped using satellite photography. The modern form of the Great Wall was built during the [[Ming dynasty]] (1368 - 1644). The claim that the wall can be seen from space is an urban legend. | The '''Great Wall of China''' is any of several extended frontier fortifications in northern China.
