Dienstedter Karsthöhle, Cave system and heritage monument in Stadtilm, Germany.
The Dienstedter Karsthöhle is a cave system in Stadtilm that penetrates the southern slope of Schenkenkopf Mountain for approximately 150 meters. It sits about 340 meters above sea level and roughly 23 meters above the Ilm River.
Felix Gebser discovered the cave in 1957, which prompted archaeological investigations that uncovered pottery fragments, bone tools, and clay vessels. These discoveries revealed that people had lived in the area during prehistoric times.
The Museum of Prehistory and Early History of Thuringia conducted excavations until 1982, uncovering remnants of fire sites and ancient artifacts.
The cave is open to visitors only on guided tours with provided safety helmets, which require advance booking. Access is seasonal, as the site closes during winter months.
The formations inside show traces of erosion patterns from two to five million years ago when the ancient Ilm River cut through limestone. These geological markings are visible to visitors and offer a window into the area's landscape history.
