The Great Wall of China is a world-renowned architectural marvel and historical landmark that stretches across the northern part of China. It is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along the northern borders of China to protect against invasions by nomadic tribes. The wall was constructed, rebuilt, and maintained between the 5th century BC and the 16th century to protect the northern borders of the Chinese Empire during various dynasties.
