The Great Wall of China begins in the Hebei province in Shanhaiguan in the east and ends in the Gansu province at Jiayuguan in the west. It stretches more than 12.4 miles.
The Great Wall was constructed during many centuries on China's northern border. It was created as a defense measure and expanded during successive Empires to defend China against potential invaders.
The name "The Great Wall of China" is a European appellation. The Chinese call the Wall the "Long Wall of Ten Thousand Li." The Wall includes watch towers, shelters, fortresses and horse tracks. It is a national symbol of security and safety.
