De Broekmolen is a smock mill in Broeksterwâld, Friesland, Netherlands which has been restored to working order. The mill is listed as a Rijksmonument, number 11678.

History

De Broekmolen was built in 1876 by millwrights Wietse Jurjen en Comp. In 1911, Patent sails were fitted. This work was done by millwright Meindert van der Meulen of Dokkum. A new windshaft was fitted in 1915 at a cost of ƒ600. A new pair of sails were fitted in 1923 at a cost of ƒ565. The sails were fitted with Dekker streamlined leading edges in 1937 by millwright Westra of Franeker. A diesel engine was installed as auxiliary power in 1961 and the Archimedes' screw was renewed. The mill ceased working a few years later. The mill was restored in 1975. Common sails were fitted as part of the restoration. The mill was sold to Stichting De Fryske Mole (English: Frisian Mills Foundation) in 1977. New sails were fitted in 2008.
