The Hook Lighthouse in Co: Wexford, Ireland is a unique example of a medieval lighthouse. It dates from the early 13th century and was a major feat at the time of its construction. Purpose built as a lighthouse, it has served sailors and shipping for 800 years, apart from a short closure during the 17th century. It is thought to be one of the oldest operational lighthouses in the world. When the Tower of Hook became fully automated in 1996 and no longer needed resident keepers, it was decided to celebrate its uniqueness by opening it to the public.
