The Great Wall of China
The Great Wall of China – one of the Seven Wonders of the medieval World - was built to protect the Chinese Empire from other military groups. It is made of stones, bricks, earth and other materials. It is built along an east-to-west and stretches from Shanhaiguan in the east, to Lop Lake in the west. The length of all Chinese defense walls built is approximately 31,070 miles.
