}} The Chicago Harbor Lighthouse is an automated active lighthouse, and stands at the end of the northern breakwater protecting the Chicago Harbor, to the east of Navy Pier and the mouth of the Chicago River. ==History== It was constructed in 1893 for the World's Columbian Exposition and moved to its present site in 1919.〔 The United States Lighthouse Board prominently displayed "its 'state of the art' wares and engineering achievements." Prominently featured was "the engineering marvel" of Spectacle Reef Light and a skeletal cast iron lighthouse tower. Also displayed were a number of Fresnel lenses, including a stunning Third Order Fresnel lens which previously was awarded first prize at a Paris glass exhibition. The lens featured alternating red and white panels, and had been ordered for installation in the new lighthouse at Point Loma Light (new) in California. The coincidental conclusion of construction of the new Chicago Harbor light and the close of the Exhibition prompted the Lighthouse Board keep the lens in Chicago, and thus the lens was installed in the lantern room of the new tower.〔 Surrounded by rip rap, the structure has several levels: a concrete base and two red roofed buildings with a tapered white cylinder between them which is topped by a parapet and the light itself. In 1917 the breakwater was renovated. At the time, the lighthouse was moved to its present site, and its attached fog signal room and boathouse were built.〔 The design is "unique . . . similar to that of the offshore sparkplug towers, but this tower is taller." Except for the additions made at the time of the move, it "bears some resemblance" to the Rock of Ages Light near Isle Royale on Lake Superior, which is its contemporary. The lighthouse was listed on the National Register of Historic Places on July 19, 1984, and later was designated a Chicago Landmark on April 9, 2003. The original Third Order Fresnel lens was removed, and is now on display at Cabrillo National Monument in California.〔National Park Service (Maritime Heritage Program, Inventory of Historic Lights, Chicago Harbor Light. )〕 It had been originally intended for and was destined for the Point Loma (California) light, but was diverted (for almost a century) and kept in Chicago following its display at the exposition. In 2005, the light was declared excess by the Coast Guard. It was offered at no cost to eligible entities, including federal, state, and local agencies, non-profit corporations, and educational organizations under the provisions of the National Historic Lighthouse Preservation Act of 2000. After an unusually long delay,〔 United States Secretary of the Interior Kenneth Salazar initiated transfer to the City of Chicago on February 24, 2009.〔(Chicago Lighthouse transfer. )〕 The city had designated the lighthouse a Chicago Landmark on April 9, 2003.〔 The Lighthouse's "significant role in the development of Chicago" is commemorated in a relief sculpture, entitled ''The Spirit of the Waters'' located near the LaSalle Street entrance of Chicago City Hall.〔 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「Chicago Harbor Light」の詳細全文を読む スポンサード リンク
