The Great Wall of China
The Great Wall of China - collective name for defense systems composed of natural dams, the network of forts and towers of observation, and (in the most strategic places) walls of beaten earth, brick or stone, the lining of the northern China against invasions of the peoples of the Great Steppe.
Traditionally it is assumed that the Great Wall extended from Shanhaiguan (the Gulf of Liaodong) to Jiayuguan in the mountains of Nan Shan at length about 2400 km. It is called a "Wall of 10, 000 Li".
