The Mill No. 3 is an historic polder mill located on Kortsteeksterweg in the town of Aarlanderveen. It was built in 1823 to replace an 18th century polder mill that had been destroyed in a fire earlier in the year. The mill served the old 450 hectare West Aarlanderveen polder. The Mill No. 3 was bought by the Aarlanderveen Mill Foundation in 1963, and is ran by a live-in miller. The Mill No. 3 is open to the public, and tours are available by appointment.
