Buffalo Harbor’s north and south entrance lights were established in 1903 to guide ships approaching the harbor in New York. Built as cast-iron boiler-plate towers with a distinctive white, bottle-shaped form and black lanterns, they used Fresnel lenses of different orders for the two lights. The south light stands on the Stony Point breakwater on a dressed-stone and timber foundation, while the north light was built on a concrete pier set on a crib and was later relocated. Automated in 1935 as Great Lakes light stations shifted away from resident keepers, the north light was deactivated in the 1980s, but the south light still operates.
