A smock mill is a type of windmill characterized by its tall, wooden structure that resembles a smock, a traditional garment. It features a rotating cap that allows the sails to face the wind, maximizing efficiency. Smock mills were commonly used in Europe, particularly in the United Kingdom, for grinding grain and pumping water. The design of a smock mill typically includes a square or rectangular base with a conical roof. The sails are attached to a horizontal shaft, which turns the mill's machinery. Smock mills played a significant role in the Industrial Revolution, contributing to agricultural and industrial advancements.
