A smock mill is a type of windmill characterized by its tall, wooden structure and a thatched or cloth-covered top. These mills were commonly used in Europe, particularly in England, from the 16th to the 19th centuries. The design allows the mill to catch wind from any direction, making it efficient for grinding grain or pumping water. The name "smock" comes from the garment worn by farmers, as the mill's shape resembles a smock. Smock mills typically feature four sails that rotate to harness wind power. Many historic smock mills have been preserved and can be visited today, showcasing traditional milling techniques.
