The De Grauwe Beer mill is a working corn mill located on Ouddorp in the town of Beesel. The mill was built in 1604, and upgraded to use a steam engine in 1889. The mill suffered heavy damage during World War Two, and was not repaired until 1952. Today, the De Grauwe Beer Mill is owned by the Beesel County, and maintained by a local mill foundation. The mill is open to the public every Saturday.
