Split Point Lighthouse is a lighthouse located in Aireys Inlet, a small town on the Great Ocean Road, Victoria, Australia. ==History== Originally called Eagles Nest Point, the lighthouse was constructed in 1891. It was converted to automatic operation in 1919. The original British-made first order Fresnel lens is still in use.〔 However, the factory in Birmingham, where the lens was built, was bombed during war-time and the essential formula for making the unique lens crystal were lost, should a replacement ever be needed. A Japanese firm, consulted by the Australian Maritime Safety Authority, estimated the cost of replacing the lens at more than A$1 million. Under standard Australian lighthouse convention, red filters would usually be placed to the extreme left and right of the beam (indicating "danger zones" for a passing ship, in-line with the jagged coastline). For reasons unknown, the Split Point Lighthouse operated for many years under the opposite system; although this has now been corrected. Split point lighthouse has 132 stairs from bottom to top and is 34 metres tall. 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「Split Point Lighthouse」の詳細全文を読む スポンサード リンク
