}} Bass Harbor Head Lighthouse is a lighthouse located within Acadia National Park in the southwest portion of Mount Desert Island, Maine, marking the entrance to Bass Harbor and Blue Hill Bay. ==History== The history of Bass Harbor Head Light dates to 1855, when it was determined that there was sufficient reason for a lighthouse at the mouth of Bass Harbor. In 1885, the U.S. Congress appropriated $5,000 for construction of the lighthouse. In 1876, construction was completed on a fog bell and tower, since removed.〔(New England Lighthouses, A Virtual Guide: Bass Harbor Head Light )〕 A much larger 4,000-pound (1800 kg) bell was placed inside the tower in 1898.〔 The house of the lightkeeper remains in its original configuration with the exception of a 10-foot addition that was added in 1900. The lighthouse was added to the National Register of Historic Places as Bass Harbor Head Light Station on January 21, 1988, reference number 87002273.〔 In 1902, an oil storage house constructed of brick was built 205 feet northwest of the lighthouse.〔 Bass Harbor's fifth order Fresnel lens was replaced in 1902 with a larger fourth order. This lens was manufactured by the French company Henry-Lepaute. This lens remains in service today.〔(【引用サイトリンク】date=2009-08-06 )〕 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「Bass Harbor Head Light」の詳細全文を読む スポンサード リンク
