The Rosmolen is a 17th century corn mill located on Oudestraat in the town of Kampen. The mill was built in the late 1600s, as a horse-drawn mill with a bovenwerk, and is the only surviving mill of its kind. The Rosmolen stands on the grounds of the Stedelijk Museum. The mill was restored in 2003, and is now used as a demonstration mill where visitors can see how buckwheat flour and other grain products are produced.
