Door to Hell, Derweze, Turkmenistan. The entire area of Derweze is rich in natural gas. While drilling in 1971, soviet geologists tapped into a cavern filled with natural gas, and caused the cavern to collapse, creating a huge hole with a diameter of 229 feet. To avoid the gas discharging and poisoning the air, they decided to burn it off. They figured it would burn out in a matter of days, but it’s been 46 years. It literally looks like the doorway to the hottest place in the afterlife. That’s a hell nope!
