The Old Mill in Castlereagh

Former corn mill complex on the River Suck, built c.1725, now derelict. Comprising east-west running range, mill race and ancillary outbuildings to rear of site. Multi-period east-west running range comprises four abutting buildings. Seven-bay two and three-storey structure to east with concrete lean-to to north side. Abutting multiple-bay three-storey central building to west with blocked integral arch to west side and integral arch to east side containing iron mill wheel with timber paddles. Single-bay three-storey building to west end with concrete upper storey. Pitched slate and corrugated-iron roof with cast-iron rainwater goods. Random coursed stone walls with quoins and remains of roughcast render to walls. Yellow brick dressings to central section. Square-headed and some segmental-headed windows. Some remaining timber battened doors. Derelict outbuildings to rear of site, with remains of mill race. Mill complex set to side of road beside river. Bridge and road have been widened so only one original dressed limestone gate pier of entrance survives. Site now bounded by concrete wall. Former hydro-electric station to south of bridge.

This mill complex, originally built by the Sandfords of Castlereagh House, comprises an interesting group of mill-related structures including an intact mill wheel, mill race and mill workers' accommodation to the east of the site. It forms a visually-striking site at the western end of the town and attests to the industrial heritage of the area.
