wikipedia : Yanartaş (flaming rock) is the Turkish name of a geographical feature near the Olympos valley and national park in Antalya Province in southwestern Turkey. 

It is generally believed to be the ancient Mount Chimaera. It is the site of dozens of small fires which burn constantly from vents in the rocks on the side of the mountain. Directly below the fires are the ruins of the temple of Hephaistos, the Greek god who was associated with fire through his role as the blacksmith to the gods.
