History

Meidenmolen was built in 1855 to drain the Dwergsmear Polder. In 1953, the water board decided to fully mechanise the mill. Meetings held on 27 December 1961 and 13 March 1962 resulted in the mill being assisted by an electric motor, but full mechanisation was not carried out. The mill was restored in 1966. The mill was sold to Stichting De Fryske Mole () on 4 May 1976. Further restorations were carried out in 1978 and 1994, the latter was carried out by millwright Thijs Jellema of Birdaard. In 2004 a new steel Archimedes' screw was fitted. In 2006, the mill was officially listed as being held in reserve for use in an emergency.
