The South Stack Lighthouse is built on the summit of a small island off the north-west coast of Holy Island, Anglesey, Wales. It was built in 1809 to warn ships of the dangerous rocks below. The lighthouse has warned passing ships of the treacherous rock below since its completion in 1809. The 91-foot (28 m)-tall lighthouse on South Stack was designed by Daniel Alexander and the main light is visible to passing vessels for 24 nmi (44 km; 28 mi), and was designed to allow safe passage for ships on the treacherous Dublin–Holyhead–Liverpool sea route. It provides the first beacon along the northern coast of Anglesey for east-bound ships. It is followed by lighthouses, fog horns and other markers at North Stack, Holyhead Breakwater, The Skerries, the Mice, Point Lynas and at the south-east tip of the island Trwyn Du. The lighthouse is operated remotely by Trinity House. The lighthouse is now open to visitors on a seasonal basis.
