Commissioners of Irish Lights as the General Lighthouse Authority for the Island of Ireland and the adjacent seas and islands, operate an all-island coastal network infrastructure consisting of 250+ onshore and offshore sites and platforms (lighthouses, buoys and other aids to navigation) with associated monitoring and communications systems. This extensive and unique network around the entire coast of Ireland sits strategically at the periphery of Europe.
