The Great Wall of China stretches over 5,500 miles from east to west. It was constructed over many dynasties starting in the 5th century BC to protect China from northern invaders. The wall we see today was primarily built during the Ming Dynasty in the 14th-16th centuries. Its purpose was to defend against attacks from Mongol and other nomadic groups living north of China. Maintaining and repairing the wall has cost over 2 million lives over its many centuries of construction and reconstruction.
