[edit] History

To help navigation towards ore docks, Congress approved funds to built the Marquette Harbor Light in 1850. Construction took place in 1852, and first lit in June of 1853. However, the initial structure deteriorated rapidly, and funds were approved in 1865 for a replacement tower.[4]

The original lighthouse included seven 14-inch Lewis lamps, and a small detached 24 by 30 dwelling constructed of similar materials to that of the tower. In 1853, the United States Lighthouse Board was created and a major system upgrade brought on an installation of a Sixth Order French Fresnel lens in 1856. The new lens was visible up to ten miles. Because of weather conditions, installation, maintenance and operation of a foghorn was integral to the operation.[4]

The current lens is a DCB-36. Putting aside questions of nostalgia, aesthetics, or appreciation for the engineering of a bygone era (as exemplified by the Fresnel lens), this iteration of lighthouse illumination is itself incredibly effective, and an endangered remnant of another bygone era.[5]

Construction of the current structure began in 1865. The 1½-story dwelling shares its design with the lighthouses on Granite Island, Gull Rock and Huron Island. It includes a set of cast-iron spiral stairs winding from the first floor to the lantern centered on the square gallery atop the tower, a decagonal cast-iron lantern was installed, and a new fixed white Fourth Order Fresnel lens with a 190° arc of visibility was assembled atop its cast-iron pedestal. The focal plane is at 70 feet above the lake, and was visible for a distance of 16 miles in clear weather.[4][6]

In 1891, a station of the U.S. Life-Saving Service began operations on the lighthouse grounds, with the station located to the west of the lighthouse, which in 1915 became part of the U.S. Coast Guard. In 1939 the U.S. Lighthouse Service also merged under the control of the U.S. Coast Guard, placing all facilities on the grounds under the same government control. As part of the U.S. Coast Guard, the site became a training station during World War II with up to 300 recruits living in the various buildings on the facility grounds.[4][7]

In 2002, a 30 year lease was signed by the Marquette Maritime Museum, which is responsible for maintenance and control of the facility. As part of their operations, thay also make the lighthouse available for scheduled tours.[4][7] The lighthouse is open and tours are conducted from 10:00 a.m. until 4:00 p.m. from May 15 through October 15.[8]

Because of its picturesque form and location, it is often the subject of photographs, drawings,[9] and even of needlepoint illustrations.[10] Built high on a bluff, it is one of the oldest buildings in Marquette.[11] It is listed in the National Register of Historical Places. It is described as the Marquette Harbor Light Station (added 1984 - Building - #84001803).[12]

Marquette Harbor Light is one of 149 lighthouses in Michigan. Michigan has more lighthouses than any other state. See Lighthouses in the United States.
