Bull Island

Bull Island (Oileán an Tairbh in Irish) or more properly North Bull Island (Oileán an Tairbh Thuaidh in Irish) is an island located in Dublin Bay in Ireland, about 5 km long and 800 m wide, lying roughly parallel to the shore off Clontarf (including Dollymount), Raheny, Kilbarrack, and facing Sutton. The island, with a sandy beach running its entire length, is a relatively recent, and inadvertent, result of human intervention in the bay. Source: Wikipedia
