The Rauher Kulm is a small basalt mountain located in the Upper Palatinate (Oberpfalz) region of Bavaria. It is located 5 km south of Kemnath. The mountain is 682 meters (2,238 ft) tall and has a 25 meter (82 ft) tall observation tower at its peak offering views of the northern Franconian Switzerland, the southern wall of the Fichtelgebirge mountain range, and the Upper Palatinate Forest.
Since 1949, the mountain has been protected as a federal monument in the Northern Upper Palatinate Forest Natural Park. It is one of the most imposing basalt mountains in Bavaria and was formed during the Paleocene-Pliocene period when a number of active volcanoes produced liquid magma, mostly due to the continental collision of Europe and Africa. As a result, not only the Alps, but a number of fissure vents and cracks, began to form throughout central Europe where magma could rise. Most of the Rauher Kulm's magma cooled below the surface.
During the Middle Ages, a castle was built on top of the Rauher Kulm, but it was destroyed after a prolonged siege during the Second Margrave War.
