There’s a small village in Turkmenistan, called Derweze. It’s in the middle of the dessert, and has a population of 350. It doesn’t have much to offer, other than a door to hell, that’s been burning for over 40 years.

In 1971, a team of geologists broke through the surface of a massive underground cavern, which caved in and swallowed their drilling rig. Worried that the cave was full of dangerous gasses, they lit it on fire to burn it off. Obviously, it caught fire and hasn’t ever stopped. The crater sits on top of one of the largest natural gas deposits in the world, and will just keep burning until the supply runs out.
