The only prehistoric relic still visible today is the semi-circular rampart, also dating to the Bronze Age, on the western side of the Pfaffenstein near the Bequemer Aufstieg trail. The embankment probably guarded the only entrance to the plateau and was surrounded by a ditch. Archaeological investigations in 1959 and 1961 estimated its age at about 3,000 years. More pieces of ceramic were discovered inside the rampart.
