The entrance to hell is a 20-meter-deep fire pit in the middle of the desert.
Turkmenistan was a part of the Soviet Union, which is no longer around.
The land in this area has a lot of oil and gas.
Two Soviet geologists tried to get gas from the site in 1971, but the ground gave way and made the crater.
The Soviets set fire to the crater to stop poisonous gas from getting out.
Because of this, the fire has never gone out since.
This is how the Darvaza crater, which has become known as the "gate to hell," was made.
At night, you can see the flames from miles away.
Turkmenistan's President Gurbanguly Berdimuhamedow told it to close for the first time in 2010.
The plan was to make more natural gas and send more of it to other countries.
But at the time, the gate of hell brought in a lot of tourists and was an important way for the local economy to make money.
The ruler decided to keep the fire going in the crater until it goes out on its own.
But in 2022, Berdimuhamedow changed his mind and again told the gate to be closed and the fire to be put out.
Because there is a lot of gas in the soil of Turkmenistan, no one knows when it will go out on its own.
