This wall was built to protect the Chinese Empire against various groups or military incursions by various warlike peoples or forces. Many walls were being built in the 7th century BC and later joined together and made bigger, stronger, and unified. Now it is called “ THE GREAT WALL”. The wall built between 220–206 BC by the first Emperor of China , Qin Shi Huang.
The Great Wall is reputed as one of the seven construction wonders in the world not only for its long history, but its massive construction size, and its unique architectural style as well. A great army of manpower, composed of soldiers, prisoners, and local people, built the wall.
The Great Wall of China is made of stone, brick, tamped earth, wood, and other materials, and built along an east to west line across northern borders of China.
Archaeological survey found that the entire wall with all of its branches measure out to be 21,196 km (13,171 mi)
