The Brennender Berg (Burning Mountain) is a natural monument located in a deep and narrow gorge between Dudweiler and Sulzbach in Saarland, Germany.
According to legend, a shepherd lit a fire at a tree stump, which propagated down through the roots to the coal seam.
A convenient starting point is the parking lot of the Dudweiler cemetery at the end of Neuweiler Straße.
Johann Wolfgang von Goethe also visited the Brennender Berg in 1770 and a commemorative plaque records the event.
We were enveloped by a strong sulphur smell; one side of the cave was almost glowing, and covered with reddish, white-roasted rock.
