The De Valk mill is a former water mill located on Molenweg in the town of Berkel Rodenrijs. The mill was built in 1772, and was originally used to drain the Berkel Polder. The De Valk Mill was decommissioned in 1929, and in 1954 it was converted into a dwelling. The mill is now privately owned, and is used as a private residence. The structure is in a good condition, but the mill is no longer functional.
