In 1971, Soviet scientists looking for oil in the Karakum Desert of Turkmenistan accidentally created what became one of the country’s most popular tourist attractions and one of the world’s most bizarre places: The “Gates of Hell.”
While drilling for oil, they hit a large cavern filled with natural gas, causing the ground to collapse into a giant hole and the rig to fall inside. In the hope that the dangerous methane gas escaping from the pit they created would burn off quickly, the scientists set fire to it. It’s been over 50 years since, and the flaming crater is still very much burning.
