Duluth North Pier Light
The Duluth North Pier Light is a lighthouse on the north breakwater at the entrance to the Duluth Ship Canal.
==History==
An 1896 project to improve harbor facilities resulted in the reconstruction of the sides of the ship canal, bracketing it in the two concrete piers which define its channel to the present.〔(【引用サイトリンク】title=Duluth Harbor North Breakwater, MN )〕 While the south pier had been equipped with a light from 1874, the north pier was unlit, and given the difficult approach (highlighted by the notorious wreck of the SS Mataafa in 1905), calls for aids were soon made. A 1908 Lighthouse Board report, in recommending construction of a light on the north pier, noted that a private aid was already being placed on the pier.〔〔〔(【引用サイトリンク】title=Duluth North Pierhead Light )〕 Appropriation was made in 1909, and a tower was erected and lit the following year.〔 The design was based off that of the Peche Island Rear Range Light, featuring a short round tower built of steel plates.〔 A fifth-order Fresnel lens from France was installed and lit with an 210-candlepower electric lamp powered from the city power grid.〔 All the lights on the canal were maintained by the same keepers; the head keeper lived in a frame house constructed in 1874 with the south pier light, while the assistants were given a brick duplex in 1913 after years of having to find boarding accommodations on their own.〔
