The Veenmolen is an historic grain mill located on Oudhuijzerweg in the town of Wilnis. The grain mill was constructed in 1823, although it is believed that there was a polder mill on the site before this date. The mill was in active use until 1947, when Thomas van der Does sold the mill to the town. The mill was restored in 1965, and partially converted to a museum. It is still in working order, and demonstrations of its operation are sometimes given to visitors.
