The 'smock mill' is a type of
windmill that consists of a sloping, horizontally weatherboarded tower, usually with six or eight sides, on top of which is a roof or cap, which can rotate to bring the sails into the wind. This type of windmill got its name from its supposed resemblance to the
smock worn by
farmers in earlier days.
Smock mills differ from
tower mills in that the latter were usually cylindrical rather than sextagonal or octagonal, and built from brick, stone or masonry instead of timber.
Smock mills exist in
Western Europe and particularly in
England, where they were common, particularly in the county of
Kent. They reached their heyday in the earlier part of the 19th century, after which the advent of
steam power started the decline of the windmill.
An example of a standing smock mill is
Willesborough Windmill in
Ashford, Kent.
Designed by the civil engineer
John Smeaton, Chimney Mill in
Spital Tongues,
Newcastle upon Tyne was the first five-sailed smock mill in Britain and the only surviving smock mill in the North East region. However, the sails and original cap are no longer in place.
