The Haulbowline Lighthouse is an active 19th century lighthouse. Described as an "elegant, tapering stone tower" it is located at the entrance to Carlingford Lough, near Cranfield Point in County Down, Northern Ireland. The lighthouse was built on the eastern part of the Haulbowline rocks, one of a number of navigation hazards at the seaward end of Carlingford Lough, which include a notable rocky shoal or bar across the mouth of the lough. The multi-purpose light was designed to help mark the rocks and, when first built, the depth of water over the bar, as well as acting as a landfall light for ships entering from the Irish Sea. Associated with the lighthouse are the leading lights at Green Island and Vidal Bank which mark the safe channel along Carlingford Lough, with Haulbowline displaying a reserve light in case of problems with these leading lights.
