The Green Mill, Oldstone Road, Muckamore, Antrim, Co Antrim

The Green Mill was a three-storey, eight-bay brick building with granite quoins, dating from between 1880 and 1899. It was located on Oldstone Road, Muckamore, County Antrim, and was demolished and replaced by a housing development. The dressings to the segmental and semi-circular windows and eaves cornice were of yellow brick, and the roof was hipped and slated. The windows were sash windows with a vertical division.

Historical maps indicate that prior to the construction of The Green Mill, a number of buildings marked 'Beetling Mills' were present on the site in 1832. The mill was described as a good, solidly built Victorian industrial building in 1969, when it was owned by Thorer U.K. Ltd, and was demolished and the site cleared in the 1990s. Part of the grounds lie within the area of the historic monument ANT50:76. The building held industrial archaeological interest, and was considered to possess monument status.
