Historic Windmills

in Finland

The technique of grinding corn into flour by using wind power to turn a circular stone died long ago but the ingenuity of the machinery keeps us fascinated just like old cars or engines do. The fact that these machines are made by hand out of wood and that not two windmills are alike makes them all the more interesting. We are taking a closer look on historic windmills in Finland.

Smock Mills

There are three types of windmills in Finland: post mills represent the oldest type; hollow post mills represent a type that dates back to the second half of the 18th century; and smock mills, which are called mamselli in Finland according to mademoiselles who wore the smocks, were also introduced in the late 18th century. Most of the surviving mills were built in the 19th century. According to Hirsjärvi & Wailes “smock mills were used by the manors; hollow post mills were built by the larger farmers, and post mills by smallholders”. All Finnish windmills are made of wood with one exception. Today most of them are painted with red earth paint, and indeed, this is known to have been the tradition since long at least in the western and central parts of the country.

Windmill technology was brought to Finland from Sweden. Windmills were mentioned for the first time in 1463 in this eastern province of the kingdom. Towards the end of the 16th century their number is known to have grown to about 400. Over the centuries the technology spread from the southwest through the whole country. Water–powered mills always dominated in areas with waterways but windmills were built in great numbers over the next three centuries where fast flowing rivers and rapids are scarce.


There was no overall information of the many windmills in Finland. The only documents with a general view are two maps—with few accompanying facts and figures—by Toivo Vuorela in his books Atlas of Finnish folk culture (1976) and Etelä-Pohjanmaan kansanrakennukset (1949). The first gives a graphic view about where the different types of windmills could be found in Finland before the First World War. The second illustrates the number of windmills in the year 1830.

For fresher information a request for a survey was sent to all regional museums in the country. The aim was to count the surviving historic windmills and get an idea of their state of repair. See our conclusion of the attained information…

Summary of Finnish Windmills

Here is the summary of a complete list of Finnish windmills, status as of spring 2014—where the condition of each windmill was evaluated roughly in three categories, A, B, C as follows:

  • condition A = good; structure, sails and machinery intact
  • condition B = OK; faults in roof or walls, eg. sails missing or machinery incomplete
  • condition C = bad; unsound or incomplete structure, sails and machinery missing

Special Thanks

The information about the number and state of the historic windmills in Finland was collected by the following curators and researchers at the regional museums in Finland and on Åland:

The glossary of windmill terminology is based solely on the available literature and Internet sources. Despite its limitations it should help those who are inspired to go on studying the subject in these languages.
