Collis Mill is a Grade II* listed smock mill at Great Thurlow, Suffolk, England, which has been restored.
Collis Mill was originally built at Slough, Berkshire. It was moved to Great Thurlow in 1807 replacing an earlier post mill. Thomas Hunt, the Soham millwright, carried out repairs to the mill in 1914. It ceased working by wind in 1915 and the sails were removed from 1920.[1] The mill was worked by a portable steam engine until 1937. The derelict mill was capless in 1959 when it was purchased by R A Vestey for restoration as a visual amenity. Restoration was completed in 1962.[2]
Collis Mill is a three-storey smock mill on a single storey brick base. It has four Common sails and the pepperpot cap is winded by a fantail.[1] It has two pairs of underdrift millstones.[3]
