There are nearly 1,600 more miles to the Great Wall of China than previously thought, according to new findings by China's Administration of Cultural Heritage and the Bureau of Surveying and Mapping. In case anyone's curious, that's about the distance from Boston to Tulsa, Oklahoma.
As part of a two-year study of the wall, researchers using infra-red cameras and GPS technology found that it now spans a total of 5,500 miles (8,850 km). The old estimate had been based primarily on historical records.
Sandstorms and other natural occurrences have covered up much of the wall over time. Most of the newly-discovered portions were built during the Ming Dynasty (1368-1644) and stretch from northeast China into the western desert, passing through 10 provinces and autonomous regions.
Contrary to popular belief, the Great Wall isn't actually one wall, but a series of defensive walls that were first constructed 2,500 years ago. They were first unified under the first emperor of China, Qin Shi Huan in 220 BC.
Researchers will continue to survey other older part of the way from the Qin and Han Dynasties (206 BC - 9 AD) as part of a 10-year protection plan of the Wall.
Unlike typical tourist pictures of the wall, many of the new sections take the form of trenches or us natural barries like rivers to serve as part of its defense, according to Chinese historian Zhu Zhewen.
Some of the best trips I have taken in China were at the Great Wall. There are heavily rebuilt portions which are great to see what it would have looked like in its heyday, and then there are the off-the-beaten path portions that are wild and crumbling.
Though it's not permitted, many travelers sneak in to sections of the "wild wall" and even camp out. The new discovery may mean even more adventure seekers will visit.
How ironic that a wall built to keep people out is now bringing them in.
