The Einsielicher Weichberger lived here from 1937 to 1956. Two social systems allowed him to live here.

Far from cars, you can unwind here. Either sit on one of the benches or on the grass and take a leisurely walk. Personally, I would refrain from riding my bike because the cyclists bothered me more in this case :)

The region is primarily known for the Höhlenburg Buchfart, also known as the Rock Castle. This is not a natural cave system but a unique rock-hewn castle built into a cliff face, distinguished as the only cave castle in Thuringia. It features 9 preserved chambers carved into a shell limestone escarpment 40 meters above the Ilm River.
The Höhlenburg Buchfart was first documented in 1348 and abandoned around 1440. Historical findings suggest an even older settlement. The site fascinated Johann Wolfgang von Goethe, who mentioned it in his writings, and the physician Georg Agricola also visited in 1551, documenting local tales of 'troglodytes' inhabiting the chambers.
Yes, beyond the unique Rock Castle, you can visit the Park Cave and the Nadelöhr in the Park on the Ilm, a natural monument offering views of Goethe's garden house and a natural bridge.

You can also find the Hermitage of Hans Weichberger, a historical site where a hermit lived for decades.
