The "Door to Hell" is a natural gas field located in Turkmenistan, near the village of Darvaza. It was created in 1971 when a drilling accident caused the ground to collapse, forming a large crater. To prevent the spread of methane gas, scientists set the crater on fire, expecting it to burn out in a few weeks. However, it has been burning continuously for over 50 years. The crater measures about 230 feet (70 meters) wide and 66 feet (20 meters) deep. It emits a bright glow, making it a popular tourist attraction. The "Door to Hell" is often visited by adventurers and photographers drawn to its unique and dramatic appearance.
