De Pankoekstermolen, Witmarsum
De Pankoekstermolen is a smock mill in Witmarsum, Friesland, Netherlands which was built in 1900. It has been restored to working order and is designated as being in reserve. It is listed as a Rijksmonument. History. "De Pankoekstermolen" was built in 1900 to drain the Oosthemmerpolder. It replaced a mill built in 1817 that was struck by lightning and burned down in 1899. "De Pankoekstermolen" was built by millwright J H Westra of Franeker, Friesland. A diesel engine was installed in the mill in 1967. Until 1975, the mill was fitted with Patent sails. Construction of a  new pumping station in 1976 made the mill redundant; the diesel engine was then removed. A restoration of the mill was carried out by millwright Westra of Franeker in 1975-76. On 21 June 1977, "De Pankoekstermolen" was sold to Stichting De Fryske Mole, the 15th mill bought by that organisation. In 2006, the mill was officially designated as being held in reserve. A new restoration was begun in 2014. It is listed as a Rijksmonument, №39438. Description. "De Pankoekstermolen" is what the Dutch describe as a "Grondzeiler".
