The Cove Island Light, located in Fathom Five National Marine Park, on the Bruce Peninsula, Ontario Canada, has stood guard, warning Great Lakes mariners navigating the treacherous narrow channel between Lake Huron and Georgian Bay, since it became operational in October 1858. ==History== Construction began in 1855 with a crew that consisted of: 7 masons/stone cutters, 10 labourers, 1 blacksmith, 1 foreman and 3 horses. One of the workmen left his mark by scratching his initials and the date in wet mortar, halfway up the tower. While under construction, the crew kept a light burning on the island by placing a lantern at the top of the unfinished tower. The lamp itself underwent several transformations starting with an Argand lamp fueled with sperm whale oil, then a flat wick coal oil lamp, replaced with an oil vapour light about 1900. Vapourized kerosene was burned to keep the beacon aglow. An on-site generator provided electricity during the 1950s and in 1971, an underwater power cable was laid from Tobermory to the island. Similar in style to the other Imperial Towers lighthouses on Chantry Island, at Point Clark and on Griffith Island, the Cove Island lighthouse has 5 sets of stairs with 15 steps each, one set with 11 steps and the final curved iron stairway to the lamp room has 9 steps (total: 95 steps). An iron door leads into the lamp room. The stone lightkeeper's cottage adjacent to the tower was built at the same time. The "new" lightkeepers house was built in 1970 a short distance from the tower. This lightstation was continuously manned from 1858 to 1991, making it the longest keeper-occupied lightstation in Ontario. The lighthouse tower, the original house and fog plant, a workshop, the assistant keeper's house and the modern lightkeeper's house make up the lightstation today. 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「Cove Island Light」の詳細全文を読む スポンサード リンク
