It was built in 1920 under the U.S. Lighthouse Service.","why_significant":"It marked a part of the Hudson long worrying to mariners and was the last Hudson River lighthouse built by the U.S. Lighthouse Service, using the styling of earlier Service towers. It is part of a thematic group on Hudson River lighthouses touching maritime history, architecture and transportation. Public affection for a children's story about it helped save it from sale in the early 1950s.","narrative":"Perched on a rocky point of the Hudson River shore beneath the George Washington Bridge, this small lighthouse in Fort Washington Park was completed in 1920. Its tower is a fourteen-foot-six-inch-wide cone of curved, welded steel panels set on a poured concrete base, rising forty feet and sixty-one feet above the water. Cast-iron hoods in the Renaissance style cap the windows, which are filled with porthole plates. A fog bell worked from inside the tower, though the bell and its machinery are gone. Mariners had been concerned about this stretch of river since 1889, when two lighted stakes were placed there. Congress funded a proper light in 1920, making it the last Hudson River lighthouse built by the U.S. Lighthouse Service. Once the bridge carried the warning lights, the lighthouse lost its purpose. Public interest, sparked by a children's story, led the Coast Guard to offer it to New York City's parks department in 1951.","period_of_significance":null,"architect_builder":null,"architectural_style":"Conical steel plate tower with Renaissance-style cast-iron window hoods, following earlier U.S. Lighthouse Service designs","criteria":[],"status_note":"No longer in use as a lighthouse; the doors have been welded closed.
