The light flashes white every ten seconds. ==History== In 1855 the Lord Commissioners of the Admiralty requested the installation of a lighthouse in addition to the harbor light at Douglas Harbour. A parliamentary report at the time revealed that the light already existing in Douglas had been out of operation since 1850. There were originally two lighthouses, one on the pier, which had to remain a harbour light, and the Douglas Head Lighthouse. The Douglas Head Lighthouse is the only sea light between the Calf of Man and the Point of Ayre - some away. Structural problems required the lighthouse to be rebuilt in 1892. The foghorn, known locally as 'Moaning Minnie', was added in 1908. It caused many complaints in Douglas, and it was later moved around the head to reduce the upset it caused to local people. The lighthouse became automated in 1986. Recently, a new public footpath was constructed by the Commissioners from the top of Port Skillion down to the Lighthouse for the benefit and enjoyment of tourists and sightseers. 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「Douglas Head Lighthouse」の詳細全文を読む スポンサード リンク
