Hook Lighthouse

The Hook Lighthouse (Irish: Teach Solais Rinn Duáin; also known as Hook Head Lighthouse) is a building situated on Hook Head at the tip of the Hook Peninsula in County Wexford, in Ireland. It is one of the oldest lighthouses in the world and the second oldest operating lighthouse in the world, after the Tower of Hercules in Spain. It is operated by the Commissioners of Irish Lights, the Irish lighthouse authority, and marks the eastern entrance to Waterford Harbour. The current structure has stood for over 800 years.
