Selected study unit - Windmill Study Unit

In 1965, João Miguel dos Santos Simões from Portugal coined the term "molinology" to describe the study of mills, whether powered by the wind or by other means. The mills can be used to move water, grind grains, saw wood, or any of a number of other tasks that could benefit from mechanical power. The Windmill Study Unit was founded in 1974 to unite philatelists interested in molinology, especially windmills. But collectors in this study unit also include items that depict the history and technology of mills and the tasks that they perform. Membership in the Windmill Study Unit includes a subscription to the quarterly journal Windmill Whispers. The study unit's website,, has pictures and additional information on mills and their appearances on stamps of the world.
