The Rosoliemolen is a 19th century windmill located on Schelmseweg in the Arnhem Open Air Museum. The mill was built in 1830, and was originally used as an oil mill. In 2004, the mill underwent extensive restoration work, thanks to funding from the Lottery. The mill can regularly be seen in operation, and visitors can purchase oil produced at the mill from the neighbouring shop. There is also a small museum containing traditional farming tools and other items.
