Greenbridge Works

Greenbridge Works is a cotton spinning mill, originally known as Hall Carr Mill, likely built in the 1830s. The structure is made of watershot coursed sandstone and features a two-span slate roof with skylights, arranged over two levels. It has a rectangular double-pile plan measuring 22 by 4 bays, with an engine house on the east side and a stair turret on the west side. The mill stands four and a half storeys tall, with its south end built into the rising hillside. There are bands on four levels and plain vertical rectangular windows on all floors, except for the tall round-headed windows on the second level of the engine house. The windows on the right side of the gable end facing the road have been altered to serve as doors for a fire escape. A round archway is present at the ground floor of the first bay on the left side wall. Inside, slim iron columns support wooden beams in stirrups. Historically, the mill may have been water-powered, as it was built over a culvert. By 1854, it was occupied by J.H. Ashworth & Co., cotton spinners and manufacturers. A detached chimney associated with an underground flue is located about 50 meters south of the mill, set on the hillside.
