Slagdijkstermolen is a smock mill in Finkum, Friesland, Netherlands which has been restored to working order. The mill is listed as a Rijksmonument, number 24540.[1]


Slagdijkstermolen was built in 1864.[2] It drained the Slagdijksterpolder, which was 1,350 pondemaat (500 ha; 1,230 acres) in extent. In 1931, a diesel engine was placed in the mill and a new Archimedes' screw fitted. The sails were removed in 1938, and the cap was removed in 1952.[3]

In the 1980s, plans were made to restore the mill.[4] The Slagdijkstermolen was sold to Stichting De Fryske Mole (English: Frisian Mills Foundation) on 17 December 1985.[2] In 2006-07, the mill was restored with €60,000 being granted by the province of Friesland towards the costs.[3] The new cap was fitted on the mill on 20 September 2007.[4] The restoration incorporated parts from the Cammingha-Buurstermolen, Leeuwarden which had burnt down. The mill was officially opened in May 2009.[3] The mill forms a pair with the nearby Balkendsterpoldermolen, Oude Leije.[4]


Slagdijkstermolen is what the Dutch describe as an achtkante grondzeiler - a smock mill whose sails reach almost to the ground. It is a two-storey smock mill on a single-storey base. The mill is winded by tailpole and winch. The smock and cap are thatched. The sails are Common sails.[1] They have a span of 18.00 metres (59 ft 1 in).[4] The sails are carried on a cast-iron windshaft. The axle of the Archimedes' screw is 525 millimetres (20¾ inches) diameter and the screw is 1.49 metres (4 ft 11 in) diameter. The screw is inclined at 26½°. Each revolution of the screw lifts 722 litres (159 imp gal) of water.[1]
