The Mordloch is a water-bearing cave - in technical terms: an active vadose cave - in the Roggental near Steinenkirch , a district of Böhmenkirch in Baden-Württemberg . With currently proven 4,382 meters, the cave ranks 18th among the caves in Germany and 4th among Baden-Württemberg caves in terms of total length. The emerging water flows over the Mühlbach, which flows parallel to it in its floodplain, after about one kilometer at the Obere Roggenmühle in the Eyb .

The front area of ​​the cave can be entered with simple equipment , but diving equipment is required from the first siphon after 80 meters. As with all active water caves, driving into it is very dangerous and should only be undertaken by experienced cave walkers.


The legend of the Eybach castle forester entwines around the murder hole. He is said to have been murdered by poachers and his body hidden in the cave, where the forester's loyal dog found it after a long search. The murderer later had a fatal accident on the Ravensteiner Felsen and confessed to the murder before his own death.
