Built between 1790 and 1820. In poor condition when listed in 1986, since when the central section of the S barn frontage containing door, window and oculus has collapsed.


Windmill tower and attached range to E. Tall (13m), tapering, circular windmill tower partly clad in ivy. Coursed limestone blocks (partly rendered to N side) of 4/5 storeys; floors and cap with sails and other machinery all gone. Plain window and door openings with deep reveals and formerly timber lintels, some ironwork supports for external gallery remain halfway up.

Attached on E side are ruinous rubble walls of rectangular threshing and winnowing barn. Remains of 2-storey, 3-bay S elevation with semi-circular arched heads to surviving openings including lunette. Dressed voussoirs, square opening for drive machinery links through the adjoining walls.
