Horseshoe Reef Lighthouse (ruin)

History

The rocks at the head of the Niagara River, where Lake Erie narrows toward the falls, were a hazard for ships bound into Buffalo. The best spot for a light was on the Canadian side of the water boundary, so the United Kingdom ceded one acre around the reef to the United States on December 9, 1850, on condition that a lighthouse be built.^[1] Congress provided the money on March 3, 1851.^[1] For a time the site was a small piece of American territory surrounded by Canadian water.^[1]

Building in the fast current was difficult, and the light was not shown until September 1, 1856, through a Fresnel lens.^[1] The Lighthouse Directory describes the station as a square wooden keeper's house with a lantern on the roof, raised on an iron frame above a square stone foundation, and notes that it actually stands on Middle Reef rather than Horseshoe Reef.^[2]

The border was later adjusted so that the lighthouse lies on the U.S. side. Wikipedia attributes this to a 1908 treaty, and the Lighthouse Directory says the line was moved about 100 feet west in 1913.^[1,2] The light itself was given up about the same time: Wikipedia dates the end to August 1, 1919 or to 1920, and the Directory to 1930.^[1,2]

After that the station was simply left to the weather. The wooden house rotted and collapsed, leaving only the iron framework and the lantern, and a December 2021 storm tore away part of the foundation.^[1,2] Cormorants now nest on the ruin.^[1] It can be seen from the Buffalo Main Lighthouse grounds and from harbour tours, but it is reachable only by boat and should not be approached.^[2]
