Digital DeconstructionGreat Wall of China more than twice as long as previously thought
According to a recent BBC News report, the Great Wall of China, which is a series of fortifications made of stone, brick and rammed earth, was subject to a recent archaeological survey that found its total length to be 21,196 km or 13,171 miles.
Based on a 2009 study, it was thought to be much shorter at 8,850 km. The Great Wall, which was built in 500 BC to protect China’s northern border, is the world’s largest manmade structure.
Early calculations were just a bit off. Great to hear we now have an accurate figure.
