Hexenloch Mill

"Witch's Hole Mill"), formerly the Dreistegen Mill (Dreistegenmühle), lies in the ravine-like Hexenloch (also sometimes called the Hexenloch valley, but not often by the locals) in the Black Forest in Germany between St. Märgen and Furtwangen in the parish of Furtwangen-Neukirch.

In 1825, the part with the smaller water wheel was built as a nail smithy.

Later, the part with the larger water wheel was built as a sawmill.

Eventually the nail smithy was turned into a workshop for the clockmaking works.

The mill and restaurant are open daily all year round, with the exception for 2 weeks in March.
