The watermill lies on the Marr Beck, and had a long mill race and two ponds, which are now dry.
A mill in Coulton was first recorded in the 13th century, and probably occupied the same site as the present building.
The byre has two storeys and three bays, and contains doorways and windows, and in the gable end are dove holes.
[4] Inside the mill, much of the 18th- and 19th-century timber machinery survives, which was used to grind corn to make flour.
The building is Grade II* listed on account of its technological and historical interest, role in local economic history, and as an example of vernacular architecture.
