The Zwanburgermolen is an historic polder mill located on the Zwanburgerpolder in the town of Warmond. The mill was built in 1805 by Simon Paddenburg of Warmonder. The mill originally served the 233 hectare Zwanburgerpolder. The polder would be drained in the spring, and allowed to flood again during the winter. The Zwanburgermolen was bought by the Rhineland Mill Foundation in 1960. The mill is in good condition, and is open to the public. Tours of the Zwanburgermolen are available upon request.
