Dublin Bay (Irish: Cuan Bhaile Átha Cliath ) is a C-shaped inlet of the Irish Sea on the east coast of Ireland. The bay is about 10 kilometers wide along its north-south base and 7 km in length to a head in the center of Dublin, stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is located in the northwestern part of the bay, where one of the two major coastal sandbanks low, and has a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognized wildfowl reserve.Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: denfloden Liffey, the River Dodder flow received less than 1 km inland, River Tolka and various smaller rivers.
The metropolitan area in the city of Dublin surrounds three sides of the bay (north, west and south), while the Irish Sea lies to the east. Dublin was founded by the Vikings at the point where they could ford the River Liffey with the first wattle bridge up from the estuary. The city spread from its birthplace, around what is now James Gate area, along the coast, north-east towards Howth and southeast toward Dalkey.
The bay is fairly shallow with numerous sandbars and rock formations, and was notorious in the past for the shipwreck, especially when the wind was from the east. Until modern times, many ships and their passengers lost along the treacherous coast from Howth to Dun Laoghaire, less than a kilometer from the beach. Early maps of the bay show accurately narrow fairways and berthing areas.
The bay had two coastal sandbars, North Bull and South Bull. With the construction of the Bull Wall, started the North Bull to build up rapidly, forming North Bull Island (often simply “Bull Island”). The south wall had been built earlier – the Great South Wall – but did not result in the formation island, South Bull remaining today an area of wetlands and other string. In addition, several offshore sandbars, especially Kish Bank (on which a lighthouse stands).
From north to south, Dublin Bay beaches at Sutton Beach, Dollymount Strand on the North Bull Island, Sandymount, Seapoint and south of Dun Laoghaire. The remaining are either rocky coast (with cliffs on Howth Head, for example) or mud coming up to the dykes. In most areas, the ground slopes gently down to the sea, but apart from Howth Head, there are bluffs along much of the coast Raheny, sharper and hills just inland of Monkstown and Old Dunleary.
Over 500 crew and passengers (mostly military personnel) were lost when the steamship RMS Leinster was torpedoed and sunk by German U-Boat UB-123 October 10, 1918. She is 33 meters (108 feet) of water vid53 ° 18.88 ‘N 5 ° 47.71’W.
In 1972, the Dublin Port and Docks Board proposed to build an oil refinery in Dublin Bay. The plan strongly opposed by environmentalists, including Dublin City Councillor Seán D. Loftus, because there is a serious risk of pollution. Loftus, a lifelong campaigner for Dublin Bay, changed his name by deed poll to “Seán Dublin Bay Loftus” when standing for election to the Dáil.Although he was not elected, he managed to publish the issue and the proposal eventually turned down by the Minister of Local Government, James Tully. (Loftus later changed his name by deed poll to “Seán Dublin Bay Rockall Loftus’ as part of a campaign to press the Irish government to make a territorial claim on Rockall island off County Donegal). Loftus also led opposition to the 2002 and subsequent applications from Dublin Port Company to fill in 52 acres (210,000 m 2 ) in Dublin Bay. Other proposals for the Gulf have included a proposal to build giant underwater gas storage tanks, and padding near the lagoon behind the North Bull Island to form an amusement park.
During the summer of 2010, An Bord Pleanála refused permission to Dublin Port Company to proceed with its plans to filling another 52 acres (210,000 m2 ) in Dublin Bay.  The proposed padding, which has fiercely resisted by the residents, [2 ] politicians,    environment and others around the Gulf for over 20 years,  was rejected at one point. An Bord Pleanála refused nine out of ten of its own inspector recommendations for rejection, but refused permission on the grounds that it was not convinced that the proposed development would not adversely affect the integrity of the South Dublin Bay and River Tolka Estuary proposed Special Protection and negative affect the natural heritage of Dublin Bay.  Within a few months after the decision, applied the Dublin port Company and received a pre-application meeting with an Bord Pleanála. Dublin Port Company has redrafted its proposals in relation to the SPA boundary and may send an application for the project.
Coastal flooding can occur at high tide on several points, particularly the city side of Clontarf and Sandymount.
James Joyce in much of the action in his novel Ulysses around the bay, from Forty Foot bathing place-where the character Buck Mulligan washed on Bloomsday morning to Howth, where Leopold Bloom made love to his wife Molly in rhododendrons.
