The Door to Hell. Turkmenistan
The name says it all. The Door to Hell was originally a natural gas field-cum-underground satanic lair located in Derweze, Turkmenistan. The Soviets came across this vast reserve and started to extract the gas by drilling, causing the field to collapse and form a crater. The crater started releasing poisonous gasses prompting the Soviet engineers to set fire to the crater to burn all the gas. At the time, 1971, the estimates were that the gasses would burn out in a few weeks. It has been burning for more than four decades. This is as close to Hell as you’ll ever get.
