The Maine Works in Cullybackey, Co. Antrim was a major employer in the area in the years before the Second World War. Situated in the village on the banks of the River Maine, it specialised in cotton processing and was famous for its crease-resistant resin finishes.
During the Second World War, business changed in the Co. Antrim village. The Maine Works became a munitions factory where workers assembled 6lb shells.
The Maine Works closed in the early 1960s. The demolition of many of the old buildings and chimneys took place in September 1994. Part of the site remains in use as a Eurospar grocery outlet.
