Yanar Dag (Azerbaijani: Yanar Dağ, meaning "burning mountain") is a natural gas fire which blazes continuously on a hillside on the Absheron Peninsula on the Caspian Sea near Baku, the capital of Azerbaijan (a country which itself is known as "the Land of Fire"). Flames jet into the air 3 metres (9.8 ft) from a thin, porous sandstone layer. Administratively, Yanar Dag belongs to Absheron District of Azerbaijan.
