The site of Barrowmouth gypsum and alabaster mine, located below the cliffs overlooking Saltom Bay. The remains include buildings, building platforms, enclosures, levels, spoil heaps and an inclined plane. The first known reference to gypsum here dates from 1794. The OS map of 1863 depicts three levels with five buildings and three small enclosures. Operation ceased in the early 1880s but work started again in 1888. New levels were driven and the gypsum was transported up to the cliff top via an inclined plane, powered by a steam winch. The mine closed in 1908. The monument is also visible as upstanding structures and earthworks on air photographs mapped as part of the North West Coast Rapid Coastal Zone Assessment Survey. Remnants appear to be still extant on the latest 1990 Ordnance Survey vertical photography.
