The Hexenlochmühle was built in 1825 and is one of the beautiful, typically old Black Forest mills - romantically located in a small valley, the Hexenloch, between St. Märgen and Furtwangen. It has been family-owned since 1839 and is now being run by the 4th generation “TRENKLE”. The mill was built as a sawmill. The mill wheels (the big one has a diameter of 4 m) are driven by the water of the hay stream (300 VSec.) And generate approx. 13 HP.
