Turkmenistan is a country in Central Asia and many tourists travel to the country every year to visit the 'Gateway of Hell'. There is a cave in Darwaza, Turkmenistan,which is constantly emitting hot gas like a volcano. We have read in scripture or heard from our elders well described the burning fire that punishes sinners in hell, So perhaps inspired by same kind of contemplation this cave of fire is called the 'Gate of Hell', entering where one will never return, instead burns in an instant.
