Kühlungsborn Windmill, Ground-sailer Dutch smock mill in Kühlungsborn, Germany

The Kühlungsborn Windmill is an Erdholländer (ground-sail Dutch) smock mill: a conical timber body on a brick base, with a reefing stage at ground level. Its four sails were fitted with a Ventikante and a chain-operated Drehheck in 1936. A wind rose replaced the tail pole around 1900.

A mill in Brunshaupten was first recorded in the Mecklenburg State Calendar in 1791 and called an Erbwindmühle in 1841. Around 1900 it received a wind rose and lost its tail pole; in 1910 miller Haacker bought it for 40,000 marks. Renovations in 1913 and 1936 replaced the sails and added a chain-operated rotating hatch.

The mill's name refers to its type: an Erdholländer, a Dutch-style smock mill built on ground level rather than on a raised mound. The miller's family, the Haackers, ran it until 1961, when they fled to Hamburg; the building then stood empty until its 1987–1991 restoration. Since a 2010–2011 conversion the former mill rooms serve as a holiday flat.

The mill stands in the Kühlungsborn district of Brunshaupten, where it was first recorded in 1791. It has been a holiday flat since the 2010–2011 conversion, so the interior is not open as a museum; the building is viewed from outside. The mill is a listed monument, and the 1936 jalousie sails with vent edge and the chain-operated rotating hatch can be seen on the exterior.

The mill's 1936 refit added a Drehheck, a rotating hatch opened and closed by flyweights on rods and operated from outside with a chain. In 1953 a double roller mill and a centrifugal sifter raised capacity to one tonne of fine flour a day, and a peeling machine allowed barley flakes, groats and grits.
