The Swaen Mill is a working corn mill in the town of Nieuw-Beijerland The mill was built in 1703, and was in active use until 1958. A large part of the interior was removed in the 1960s in order to make the mill suitable for living in. The mill was restored recently, and is now operated on a voluntary basis. The mill is open to visitors each Saturday, and visits can be arranged by appointment on other days.
