Illinois is a state steeped in history. Some good, some not so good and some downright scary. Over the years we have seen our share of things come and go. But did you know that there is an abandoned underground military base? Or an equally creepy military research facility? Or that there once existed a top secret scientific base? There's also an abandoned secret bunker believed to have been built in the 70's for an unknown purpose.

There are teams of people that go out and explore these places and post lots of videos on the internet. We would advise you not to do this on your own because of the unknown risks and dangers involved. Instead check out this video of abandoned Illinois. If you know of any other places to add to the list leave a comment.
