There are many photos and videos on the internet of «Door to hell», where you can watch fire erupting in the middle of Darvaza village. The view of the flame burning in the desert is bewitching and intriguing. But not many have an idea how this wonder appeared, located in 266km to the north of Ashgabat city.~The Door to Hell was created by mistake in 1971 when the Soviet drilling rig accidentally punched into a massive underground natural carven. This caused the ground to collapse and the entire drilling rig to fall in. After the crater was created geologists intentionally set it on fire to prevent the spread of gas. It was the only way to end a potential environmental catastrophe. Geologists thought the crater would only burn for a few weeks, but it has now been burning non-stop since 1971. It is almost 50 years, and geologists still have no idea how much longer it will burn for.
Definitely place you should visit. It is just amazing!
