Quick answer：

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 of the Eurasian Steppe. Color pictures of the Great Wall often capture its vast length, ancient architecture, and the surrounding natural landscapes, highlighting the wall's historical significance and architectural beauty.
