Ypey Mole is a smock mill in Ryptsjerk, Friesland, Netherlands which was built in 1911. The mill has been restored to working order. It is listed as a Rijksmonument.
History[edit]
Ypey Mole was originally built in 1858 at Zwartewegsend, where it was in use until the Autumn of 1958 when the sails were damaged. The mill was restored in 1959 by millwright De Roos of Leeuwarden, Friesland. In November 1970, the mill was set on fire by some children. The fire brigade was able to prevent the mill being destroyed. The mill was moved to its current site in 1981 and restored by millwright Tacoma of Stiens, Friesland. Ypey Mole was sold to Stichting De Fryske Mole on 10 May 1982, the 31st mill acquired by that organisation.[1] The mill is listed as a Rijksmonument, №35687.[2]
