A Tower Mill is a type of windmill characterized by its tall, cylindrical structure. It typically features a rotating cap at the top, which allows the sails to face the wind for optimal energy capture. Tower mills were commonly used for grinding grain into flour, utilizing the wind's power to turn large millstones inside. These mills originated in Europe during the Middle Ages and became popular in the 18th and 19th centuries. Unlike traditional post mills, which have a wooden frame that pivots, tower mills remain stationary, making them more durable and efficient. They are often associated with regions like England and the Netherlands.
