Everyone has seen pictures of China's Great Wall before, but most of those images come from a handful of viewpoints just outside of Beijing, where all the tourists tend to visit.
Given that the wall stretches for over 5,500 miles, there's quite a bit more that you almost never see.
While the tourist areas are well-maintained and often renovated, much of the wall is being reclaimed by nature.
A few years ago, Kuriositas gathered up a whole bunch of photos of various parts of the Wall. It's striking to see just how drastically different the Great Wall looks.
