Cape St George Lighthouse was a lighthouse that stood near Jervis Bay Village, Jervis Bay Territory, Australia. It was located about south of the southern entrance to Jervis Bay. Constructed in 1860 it was active until 1889. The tower was destroyed between 1917-1922 to avoid confusion in daylight. The ruins remain and are listed on the National Heritage List. ==History== The recommendation to build a lighthouse on the vicinity was made in 1856. However, despite the fact that the Pilots Board, which was the controlling authority, was not consulted, £5000 were allocated and a tender was accepted. Controversy started even before construction, when the Board received numerous communications and reports questioning the angles of visibility of the site from the north and south and its proposed and actual locations, which proved to be five miles apart. Finally, when the Pilots Board examined the site, they reported that the initial map prepared by Millington and Dawson suffered from "discrepancies of so grave a character that it is impossible to decide whether either position marked on the map really exists." They also questioned whether the facility will be visible from the required approaches. Nevertheless, despite these facts and further disagreement by a majority of the Board, the lighthouse was commissioned on 1 October 1860. The resulting light was not visible from the northern approach to Jervis Bay, and was barely visible from the southern approach. When inspected by members of the Pilots Board it was found that on top of the inaccuracies, the contractor built the light north of the intended site, as it was closer to the quarry he was obtaining the stone from. Later, a Select Committee was appointed by the New South Wales Government to investigate the errors in locating the lighthouse. The committee found out the Board had been grossly negligent in approving a location without prior inspection and in relying on maps of dubious accuracy. In conclusions it reported that "errors - very grave errors, highly censurable - have been committed in the erection of this lighthouse." From 1864 to 1893 there were twenty three ships wrecked on the South Coast of New South Wales in the vicinity of Jervis Bay. The light was eventually replaced in 1899 by Point Perpendicular Light in Point Perpendicular, a much more suitable location for a lighthouse on this part of the coast. The lantern was removed and later used in the Crookhaven Heads Light, built in 1904. After the commissioning of the new light, it was considered that the confusion of having two towers in close proximity to one another would be a hazardous to navigation in daylight, especially during foul weather. As a result, the Cape St George Tower was unceremoniously used from 1917 to 1922 for target practice by the Royal Australian Navy and destroyed.〔According to "SeaSide Lights" explosive charges were used "Near the turn of the century".〕 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「Cape St George Lighthouse」の詳細全文を読む スポンサード リンク
