History

The original lighthouse on the location was constructed in 1889 when the second breakwater for the harbor was built. This light stood until 1934 when the present lighthouse was constructed. In 1936 an attached one story keeper's quarters was added.

On December 4, 1942, a boat used to transfer keepers of the light capsized during a change of keepers. Six coast guardsmen died in this incident. The station remained manned until 1968 when it was automated.

The original fourth order Fresnel lens

 was removed to the H. Lee White Maritime Museum in Oswego in 1995. In December 2000 the lighthouse was added to the National Register of Historic Places.

It is the only lighthouse of four in Oswego still standing. The light is currently solar powered.

Construction

 that extends 17 feet (5.18 meters) above the mean surface of the lake. The caisson has three feet (0.91 meter) thick walls.

The superstructure has bolted steel plate and iron walls, roof, doors, window shutters. It has a one-story hipped roof

A square hip roof is shaped like a pyramid. Hip roofs on the houses could have two triangular side...

 living quarters with a three-story tower at the north east corner of the caisson.

The caisson contains a large basement and is penetrated by double steel doors at the south where a tender may be landed to transfer personnel or supplies and a steel door at the west, leading to the breakwater. Recessed ladders are found at both elevations for access to the doorways and deck above.

The first floor level encloses the living quarters. The interior includes living room, bedroom, kitchen, hallway and bathroom areas. Finishes include plaster walls, vinyl-asbestos floor tiles and varnished wood trim throughout. A steel plate chimney rises through the roof at the southwest corner of the light. The fourth level has a lantern/watch deck and is surmounted by a conical roof with ball finial.

On June 1, 2006, the light station was declared surplus, and the application for transfer under the National Historic Lighthouse Preservation Act

of 2000 is complete and it has been recommended for transfer to the City of Oswego.

On May 18, 2009, The General Services Administration conveyed the Oswego West Pierhead Light in New York to the city of Oswego. Acting Regional Administrator Glenn Rotondo signed the deed under the National Historic Lighthouse Preservation Act. Mayor Randolph Bateman received the deed on the city’s behalf. The conveyance, which includes the light and keeper's quarters, will become part of the city's waterfront access program. It will remain a working navigational aid maintained by the U.S. Coast Guard.
