Darvaza gas crater, also known as the 'Gateway to Hell', is located in which country?

The Darvaza gas crater also referred to as the Door to Hell or the Gates of Hell, is a natural gas ground in Turkmenistan that disintegrated into a cavern. There are no meticulous statistics of how the crater sparked, and some information is contested. One of the more theoretical approaches holds that Soviet geologists deliberately set a fire in 1971 to avoid the growth of methane gas and that it has been burning ever since. The gas crater is 5,350 m2 in size. The crater attracts a lot of the tourist population and has become a tourist destination. The immediate region is also well-known for its wild desert camping.
