The Great Wall of China (220 B.C and 1368 – 1644 A.D.) China
The Official New 7 Wonders of the World
The Great Wall of China was built to link existing fortifications
into a united defense system and better keep invading Mongol tribes out
of China. It is the largest man-made monument ever to have been built
and it is disputed that it is the only one visible from space. Many
thousands of people must have given their lives to build this colossal
construction.
