Howth Harbour

Howth (from Old Norse: Hovuð meaning "head", called in Irish: Binn Éadair) is located on the peninsula of Howth Head, on the north side of Dublin Bay. Originally just a small fishing village and surrounding rural district, Howth is now a busy suburb of Dublin, with a mix of dense residential development and wild hillside, all on the peninsula of Howth Head which is connected to the rest of Dublin via a narrow strip of land. Howth is also home to one of the oldest occupied buildings in Ireland, Howth Castle.
The island of Ireland's Eye, Special Area of Conservation, lies about a kilometre north of Howth harbour, with Lambay Island some 5 km further to the north. A Martello tower exists on each of these islands with another tower overlooking Howth harbour and another tower at Red Rock, Sutton. These are part of a series of towers built around the coast of Ireland during the 19th century.
