During the Cold War era, Chairman Mao built a vast underground city under Beijing. The city was built in hopes that if war did erupt between China and other countries (most notably Russia) that the city’s inhabitants would be able to retreat and still have a somewhat livable life underground.
Of course, the city was never used in that way but it still exists today and apparently there are tours of it if you go to the right place and know the right people. I’d love to go here and just roam around.
If you aren’t satisfied with the video above, you can check out some images over at Vice magazine.
