Gußmannshöhle, Show cave and entrance in Lenningen, Germany.

Gußmannshöhle is a show cave in the Swabian Jura featuring limestone formations and passages carved by underground water. The natural chambers display layers and structures formed over vast periods of time.

Karl Gußmann discovered the cave in 1890, and it was excavated in 1890/91. The palaeontological yield was small: a few mammoth molars and tooth fragments. In May 1891 it opened to the public as a show cave, and an electric arc lighting system was installed that same year, removed after three months because of maintenance faults. Permanent electric lighting came in 1922.

The cave takes its name from Karl Gußmann, the explorer who first investigated it. Today visitors come here to experience the region's geological past directly.

Bring sturdy shoes and a jacket, as temperatures stay cool year-round inside. The entrance is relatively accessible, but moving through the passages requires care and moderate fitness.

The 1890/91 excavation yielded little: only a few mammoth molars and tooth fragments. The calcite floor removed when the cave was opened for visitors is now displayed in the local museum in Kirchheim unter Teck, 200 metres from the neighbouring Gutenberger Höhle.
