The Door to Hell

"Welcome to Derweze in Turkmenistan - or, as the locals have called it, 'The Door to Hell'."

Soviet geologists were drilling at the site in 1971 and tapped into a cavern filled with natural gas.

But the ground beneath the drilling rig collapsed, leaving a hole with a diameter of 70 metres.

Fearing that the hole would lead to the release of poisonous gases, the team decided to burn it off.

It was hoped that the fire would use all the fuel within days, but the gas is still burning today.

The flames generate a golden glow which can be seen for miles around Derweze, a village with a population of about 350.

The site is about 260 kilometres north of Ashgabat, the capital of Turkmenistan.
