Darvaza is a small village located in the middle of the Kara-Kum desert in Turkmenistan, an ex-soviet republic. Close by, a place has been in flames for over three decades. Known by it inhabitants as 'the door to hell', it's a true flames exhibition. It all started when a team of geologists were drilling the region in search of natural gas.
At one point during the drilling the ground collapsed leaving a large gaping hole exposed: a cavern filled with natural gas. It was such a large hole, it ended up swallowing every piece of equipment around, as well as everything in its way. Unable to go inside it, because of its amazing size and depth and the fact that it was completely filled with gas, the group had the disastrous idea to set it on fire. Their aim was to keep the toxic gases from leaving the gigantic hole... They could hardly imagine the fire would never be extinguished again.
Some say the fire should last for another 250 years, others believe it's "ad eternum", but the fact is: no one actually knows the answer. No one knows if it would be possible, or even worth it, to try to use this amazing energy source either, but the truth is this flaming crater really does looks like a scary doorway to hell.
