Clontarf, Dublin in the context of "Battle of Clontarf"

Bull Island (Irish: Oileán an Tairbh), more properly North Bull Island (Oileán an Tairbh Thuaidh), 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 known as Dollymount Strand running its entire length, is a relatively recent, and inadvertent, result of human intervention in the bay. The island lies within the jurisdiction of, and is mostly owned by, Dublin City Council, and is managed by the Council's Parks and Landscape Division.

Bull Island, which is accessed by way of a causeway bridge from Raheny and a wooden bridge from Clontarf, has the most designations of any site in the country, as a National Bird Sanctuary, a biosphere reserve, a National Nature Reserve, a Special Protection Area under the EU Birds Directive, and a Special Area of Conservation under the EU Habitats Directive, while also being the subject of a Special Amenity Area Order. It is a car-free zone. It holds a wide variety of plant and bird species, and a limited range of mammals, one reptile, one amphibian and a modest range of invertebrates; one mammal species, the hare, became extinct in the later 2010s.

Dollymount (Irish: Cnocán Doirinne), often known as "Dollyer" to Dubliners, is a coastal suburban area on the north coast of Dublin Bay, within Clontarf, on the northside of Dublin, Ireland, just east of Saint Anne's Park.

Mount Temple Comprehensive School is a secondary school in Clontarf, Dublin, Ireland. The school operates under the patronage of the Church of Ireland Archbishop of Dublin, and has, as a primary objective, the provision of state-funded second-level education to the Protestant population of northern Dublin, while accepting pupils of all religions and none. The school was established in 1972 following the amalgamation of Mountjoy School, Royal Hibernian Marine School in coastal Clontarf, and Bertrand & Rutland School.
