Between 1907 and 1956, including throughout the Second World War, Grey Point Fort in Helen's Bay, Co. Down provided coastal defences around Belfast Lough.
Grey Point Fort, constructed overlooking Helen's Bay, Co. Down was a vital part of Ireland's coastal defences, helping protect Belfast Lough through two World Wars.
By the end of the 19th century, Ireland’s coastal defences around Belfast Lough, situated at Carrickfergus Castle were deemed outdated. Belfast had grown rapidly as an industrial city and in 1904 construction began at Helen’s Bay resulting in the defences at Grey Point Fort.
