The historic building on the outskirts of Basel is now home to the Mühlemuseum (mill museum), which has a small exhibition about the history of milling. The mill was still fully functional until 1950. In the milling room it is easy to imagine how wheat, spelt and rye were ground here in Christoph Merian's time. The showpiece of the museum is the massive water wheel and its impressive gearing mechanism made of wood and steel, which is still fully functional. The miller starts up the historic water wheel twice a month. He explains the impressive mechanism and takes you on a journey back through the fascinating history of milling.
