The Kish Bank (Irish: ''Banc na Cise'')〔(Kish Bank ). Irish Placenames Database. Retrieved: 2010-10-22.〕 is a shallow sand bank about seven miles (11 km) off the coast of Dublin, in Ireland. It is marked by the Kish Lighthouse,〔(Kish Lighthouse ). Commissioners of Irish Lights. Retrieved: 2010-10-22.〕 a landmark well known to sailors and ferry passengers passing through Dublin Bay and Dún Laoghaire harbour. Many ships were wrecked on these shallows. The ''Vesper'' was lost in January 1876; the Norwegian MV ''Bolivar'' ran aground on the Kish Bank during a snow storm on 4 March 1947; both wrecks are frequently dived. A mailboat operated by the City of Dublin Steam Packet Company between Kingstown (later Dún Laoghaire) and Holyhead, the RMS Leinster, was torpedoed and sunk by a German submarine on 10 October 1918. She went down four miles (6 km) east of the Kish Lighthouse with over 500 lives lost, the greatest single loss of life in the Irish Sea. Fifty-five wrecks are listed for the Kish Bank area at Irish Wrecks Online.〔(Kish Bank ). irishwrecksonline.net. Retrieved: 2010-10-23.〕 In 2000, the Department of Marine and Natural Resources awarded licenses to allow detailed studies to be carried out on the Kish and Bray Banks in relation to the construction of a large offshore wind farm. Press reports at the time suggested 100 or more wind turbines might be erected. ==The lighthouse== Before the present Kish Lighthouse was installed in 1965, the sand bank had been signalled by a lightship since 1811. An attempt to build a lighthouse in 1842 was abandoned because of destruction caused by severe weather. The first Irish electric lightvessel, the ''Gannet'', was installed in 1954. The Commissioners of Irish Lights decided in 1960 to erect a reinforced concrete lighthouse with helicopter landing pad on top. The lighthouse was built in the Coal Harbour of Dun Laoghaire. The first section of lighthouse cracked while it was being built and had to be discarded. The second telescopic lighthouse was completed, towed to its station, extended to its full height and installed in 1965, with a projected lifetime of 75 years. The sand bank was bored in 1961 and a seismic survey revealed about of sand at the site. Construction began in Dún Laoghaire in 1963. The completed structure was towed from the harbour out to the sandbank on 29 June 1965. The tower was raised on 27 July 1965 to its full height of , with twelve floors inside, and with a wide helicopter platform on top. The lightvessel was removed on 9 November 1965 and the new lighthouse replaced it, operating at between two and three million candlepowers, depending on visibility conditions. The beam is visible for . The lighthouse was automated on 7 April 1992, and the keepers came ashore.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kish Bank」の詳細全文を読む スポンサード リンク
