The Mill No. 4 is an historic polder mill located on Kortsteeksterweg in the town of Aarlanderveen. It was built in 1801 to serve the old 450 hectare West Aarlanderveen polder. The Mill No. 4 was bought by the Aarlanderveen Mill Foundation in 1963. The mill was struck by lightning in 1990, and required some serious restoration work. The Mill No. 4 is open to the public, and tours are available by appointment.
