The Jan Pol Mill is an historic museum mill located on Molenwijk in the town of Dalen. The mill was built in 1876 by the mill maker Schiller of Dalfsen. The Jan Pol mill was in use as a commercial corn mill until 1947, and was officially decommissioned in 1958. The Jan Pol Mill has now been converted into a museum. The museum is open four days a week during the summer, and appointments can be made for those who wish to visit during the off-seasons.
