Dammelsberg, Mountain summit in Marburg, Germany.

Dammelsberg is a mountain summit near Marburg that rises about 318 meters (1,043 feet) above sea level. The terrain offers views of the surrounding landscape and can be reached by several walking routes.

The Dammelsberg is considered a possible former site of the vanished Kassenburg. For over 200 years oaks have been planted here to turn the area into a recreation area, but money often ran out and the forest was largely left to itself. The so-called Mordeiche still stands at the spot where shoemaker's apprentice Ludwig Hilberg murdered his lover Dorothea Wiegand on 9 September 1861; he was executed in Marburg on 14 October 1864, the last public execution in Hesse.

The so-called Mordeiche still stands at the spot where shoemaker's apprentice Ludwig Hilberg murdered his lover Dorothea Wiegand on 9 September 1861. A sign on the oak gives the date as "12.9.1861", probably the day forester Lorenz Reinhardt found the body. Hilberg was executed in Marburg on 14 October 1864, the last public execution in Hesse.

The Lahnwanderweg runs over the summit area, which lies within the 21.8-hectare FFH area Dammelsberg and Köhlersgrund. Because old oaks can topple, there is acute danger to life, so the wood is no longer a recreation area in the usual sense; keep to the marked trail and do not linger under the trees. A shelter hut stands on the mountain.

From the summit, visitors can observe geological formations that are typical for this region in central Germany. The viewpoint reveals the structure of the terrain and makes the natural character of the landscape clear.
