A coal seam burning since 1668. It developed to a tourist attraction named "Brennender Berg" (German for 'Burning Mountain'), even visited and described by Goethe. The burning attenuated at the end of the 18th century.
After rainfalls still small amounts of steam can be watched.
Located in the forest between Dudweiler and Neuweiler, about 6 km north of Saarbrücken.

NOTE: "Duttweiler" is a frequently used misnomer owing its emergence to a typographic error in the older literature.
