The Great Wall of China is one of the most famous building ever built in the world. It was built to protect China from the Mongol, Turkic, and other nomadic tribes trying to invade China. The wall measures 6,352 kilometers starting from Shanhai Pass on the Bohai Sea in the east, at the limit between "China proper" and Manchuria, to Lop Nur in the southeastern portion of Xinjiang Uygur Autonomous Region. The wall roughly delineates the border between North China and Inner Mongolia. It was built during the reign of the first Emperor of China, Qin Shi Huangdi between 220 BC and 200 BC.
