This feature class shows the location of Lighthouses around Ireland. The Commissioners for Irish Lights are responsible for the superintendence and management of all aids to marine navigation around the coast of Ireland and its adjacent waters. There are 80 lighthouses around the coast of Ireland. They were originally built to aid ships travelling on dangerous waters, and are still used today by mariners to determine position and safe courses. All the lighthouses are now automated, the Bailey in Co. Dublin being the last to be manned until 1997.
