A post mill built in the mid-late 18th century for the milling of cereals. A mill has stood on the site since the mid 16th centuryn although the mills are not the same one. The mill ceased work in 1870 when the sweeps were blown down. The building was used as an obsevatory for a few years from 1890, with brickwork underpinning being added to make the structure more secure. The mill was burnt down in 1952, but the brickwork and some supporting timbers remain.
