The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China to protect the Chinese states and empires against the raids and invasions of the various nomadic groups.
The Great Wall is one of the few man-made objects that can be seen from space, but not from the moon as the myth suggests. It was built in the Ming Dynasty (1368-1644) and is approximately 6000km long and stretches across North China from east to west for over 6,000 kilometers.
