Keston Windmill

Keston Windmill is a three-story wooden post mill from the 1700s with a single-story roundhouse base beneath it. Four double sails made of metal spin on a cast-iron shaft to turn the grinding machinery inside.

The mill was built in 1716 and operated continuously grinding grain until the late 1800s. A miller named William Ashby carried out major repairs to the sails in 1836.

The mill shows how people once ground grain using wind power to support daily life in the village. It represents practical know-how passed down through generations of millers.

The mill sits in a quiet village area that can be reached by local roads and explored on foot. It is helpful to check ahead about access and visiting arrangements, as hours and entry may be limited.

The year 1716 is carved directly into the main post of the structure, making it one of the oldest surviving mills of its type in the area. Visitors can see this carved date as a direct link to when the building was erected.
