The St. Ursualamolen is an historic water-driven corn and oil mill located deep within the forest in the town of Nunhems. The mill was built in 1773, and is the only virtually complete working oil mill remaining in the province of Limburg. The mill has a small wooden statue of St Ursula standing in a niche above the entrance. The St. Ursualamolen is open to the public, and there are regular demonstrations given on the mill in action.
