The Rietveldsemolen is a 17th century polder mill located on the north-eastern outskirts of the village of Hazerswoude. The mill was built in 1648 to serve the Rietveld polder. When the water board merged the polders, the mill was converted to serve the Riethoornsepolder. In 1966, the mill was decommissioned. The Rietveldsemolen is now owned by the Rhineland Mill foundation. The mill has been recently restored, and is now open to the public. Tours of the Rieveldsemolen are available upon request.
