Frohnbügel, Hermitage in Geiselbach, Germany

Frohnbügel is a secluded farmstead with a restaurant at 335 m above sea level on the slopes of the Teufelsgrund, directly on the border between Hesse and Bavaria. The Birkenhainer Straße, a trade route used since Roman times, runs past the farm, and the Schnellmichbach rises to the northwest.

In 1269 the Archbishop of Mainz transferred the Frohnbügel farm, with the Geiselbach lordship, to Seligenstadt Abbey; the monks farmed the land. In 1710 it passed to the lords of Boyneburg and was leased to Barthel Stenger of Geiselbach as farmland and a sheep farm. A restaurant has operated in the farm since 1905.

The name Frohnbügel comes from Middle High German frô (lord) and buohel (hill), meaning "Lord's Hill"; the same root appears in nearby Fronhofen. Since 1905 the farm has housed an inn, and its first landlords, Georg Adam and Katharina Heßler, advertised homemade apple wine and a milk cure; postcards from 1914 called the place a spa resort.

The farmstead sits at 335 m on the Bavarian-Hessian border, with the Birkenhainer Straße long-distance trail and the Spessartbogen trail running directly past it. The Schnellmichbach rises to the northwest; the Sölzertsberg (351 m) and Seiteberg (328 m) rise to the west. The inn has operated since 1905, so check its current opening days before setting out.
