I climbed to the top of this thing! This old historical iron furnace was located in Cumberland Gap TN, US.
This entire area was beautiful, and it was adjacent to a cool little hip town where we found a tiny rustic bar to enjoy some drinks; after exploring all day.
There is more information about how and what it was used for at the bottom of the post. I advise reading it, its filled with some wild facts.
I hope you thought it was cool!
