A smock mill is a type of windmill characterized by its wooden structure and a rotating cap that allows the sails to face the wind. The body of the mill is typically built on a stone or brick base, while the upper part, known as the smock, is covered with weather-resistant materials like thatch or shingles. This design helps the mill harness wind energy effectively for grinding grain or other tasks. Smock mills were commonly used in Europe, particularly in countries like the United Kingdom and Netherlands. They played a significant role in agricultural production from the 16th to the 19th centuries, contributing to the rise of the Industrial Revolution by providing a reliable source of power before the advent of steam engines.
