The Howth Peninsula, with its picturesque harbour, lighthouses, walks, martello towers, and portal tomb, offers magnificent panoramas over Dublin Bay. In pre-Christian times the Celtic tribes called this peninsula ‘Ben Edar’ - the mountain or hill of Edar - possibly after a chieftain of the Tuatha De Danann. There has also been speculation that the name Benn na Edar, has an environmental origin meaning ‘hills of the oaks’. It was the Danes, however who first used the name ‘hoved’ meaning head, and over the years this came to be Howth.
The Howth Peninsula is largely protected under the Howth SAAO, this includes Ireland's Eye (28 hectares), the heathland, woods, cliffs and wooded residential areas of the south-eastern half of the peninsula (519 hectares) and a 21 kilometre network of rights of-way as public footpaths.
