Norbury Mill

Norbury Mill is a watermill dating back to the early 17th century, with alterations from the 18th and 19th centuries. The mill is constructed of sandstone ashlar with stone dressings, incorporating red brick alterations. It has a plain tile roof with coped gables and moulded kneelers. The building has two storeys and four bays, with wheelhouses located to the north and south.

The east elevation features a central, segment-headed door framed by plain voussoirs and a hoodmould. C18 buttresses flank the door. To the south is a partially collapsed wall revealing the remains of a former 3-light recessed and chamfered mullion window. Further south are a low, similar 2-light window with a dripmould, a segment-voussoired arch for the mill race associated with the southern wheel, and a long slot likely for machinery. North of the central doorcase is a large, segment-headed voussoired arch for the northern mill race, with a single light recessed and chamfered window above, and two further 2-light recessed and chamfered mullion windows with dripmoulds.

The west elevation has undergone substantial alterations, but retains a segment-headed door centrally, and a 3-light recessed and chamfered mullion window above. A further inserted opening and two C17 single-light openings are situated to the south. To the north of the central door is a 2-light recessed and chamfered window, with a similar window above it, and a single-light opening below. Beyond this, the wall has been rebuilt and a C19 hoist for logs is attached.

The interior has been extensively altered, with most of the floor having collapsed. However, a staggered purlin king post roof with side struts, and a northern timber frame internal partition remain. The southern waterwheel is a low breast-shot wheel, approximately 11 feet in diameter, constructed of cast iron and wood, with a cast iron hub, rim, and shaft. This powered a single pair of millstones and a sack hoist. The pit wheel is wooden with iron gearing. The northern wheel is also a breast-shot wheel, featuring cast iron rims with wooden floats between, and a cast iron hub. A cast iron bevel wheel is located on the north side of the wheel. The mill was converted in the 19th century to a sawmill, so no millstones remain on the northern side.
