The lighthouse was built in 1857 by the U.S. Lighthouse Service.","why_significant":"It is tied to the maritime history and commercial navigation of Long Island Sound. Its design is also distinctive: a short square brick tower with a vernacular attached dwelling, built before the Lighthouse Board standardized lighthouse designs. The tower and dwelling keep a high degree of exterior integrity and the light still operates.","narrative":"Horton Point Lighthouse sits on a bluff on the North Fork of Long Island, looking north across Long Island Sound toward Connecticut. Completed in 1857, it combines a square, slightly tapered brick tower, 55 feet high, with a two-story keeper's dwelling. Around 1865-70 a second story was added to house an assistant keeper. A storage barn from 1891 also stands on the eight-acre site. The light served a busy shipping route; the keeper's log for October 1860 counted 979 vessels passing in one month. Its design is unusual for Long Island, since it predates the standardized plans the Lighthouse Board later promoted. The light was automated in 1933, ending the keeper era, and the property passed to the Southold Park District. The Coast Guard recommissioned the old tower in 1990, and it still shows a green flashing light. Part of the building now serves as a museum and exhibit space.","period_of_significance":"1857-1933","architect_builder":"U.S. Lighthouse Service (builder)","architectural_style":"Mid-19th Century","criteria":["A","C"],"status_note":"Still a working lighthouse, recommissioned by the Coast Guard in 1990.
