While it is impossible to know exactly what the Great Wall of China cost to build, modern calculations estimate the cost to be approximately $360 billion. The wall is 4,160 miles from end to end.
The Great Wall of China is the longest man-made structure in the world, and construction began between 260 and 210 B.C. RandomHistory.com reports that more than one million people died due to accidents during construction. The Great Wall was called “the longest cemetery on Earth” because of so many lost lives. It has been rumored that bodies were buried inside the wall, but that is untrue. Burying bodies inside the wall would have weakened the structure.
