Lochmühle Lohmen, Historic watermill in Lohmen, Germany

Lochmühle Lohmen is a watermill located at the entrance of Liebethaler Grund, a narrow gorge carved by the Wesenitz River through sandstone rock. The mill stands in a deep valley surrounded by high cliff walls.

First mentioned in 1559 as a grain mill, the Lochmühle was probably built shortly before, since the record notes it was "not yet fully built". A rockfall destroyed it in 1681, and it was rebuilt 30 paces upstream. A fire in 1828 led owner Friedrich August Schreiter to rebuild it with four millstones; in 1842 he obtained permission to run a tavern there.

The composer Richard Wagner spent time here in 1846 and wrote sections of his opera Lohengrin during a summer visit. A monument erected in 1933 stands as a reminder of this creative period by the famous musician.

The mill is currently not open to visitors due to ongoing restoration work that began in 2017. However, the surrounding area offers hiking trails through the gorge that are open to the public.

The 1799 cart track from Mühlsdorf was so steep that grain and flour sacks were usually carried down on donkeys' backs rather than by horse-drawn wagon. The mill's name comes from its position literally "in the hole" of the deeply cut Wesenitz valley.
