It now sits at the Long Island Maritime Museum.","why_significant":"The nomination argues it is a rare, relatively unaltered early-20th-century seafood processing building, whereas most such plants were repeatedly altered. It is the only known survivor of the turn-of-the-century Great South Bay Blue Point oyster industry. It is one of five nationally significant oyster-processing structures identified, representing the culling and shucking stage.","narrative":"Built in 1908 on the shore of Great South Bay in West Sayville, this small gray clapboard building with a cedar-shingle roof served as an oyster culling and shucking house until 1947. William Rudolph, the son of Dutch immigrants, built it for the oyster company he founded in 1895, which planted, harvested and shipped Blue Point oysters to New York and beyond. The frame structure measures about 44 by 16 feet, with a loft for storage, a shucking bench along one wall, a pot-bellied stove and seaweed insulation. A small office ell was added later. In 1974 the building was moved roughly 600 feet to the Long Island Maritime Museum grounds, restored, and opened in 1976. It is recognized as the only known survivor of the turn-of-the-century Great South Bay oyster industry and as a rare, little-altered example of an early seafood processing plant. It now interprets that industry for visitors.","period_of_significance":"1908-1947","architect_builder":"William Rudolph (builder/owner)","architectural_style":"Other: Early 20th century marine commercial","criteria":["A"],"status_note":"Moved about 600 feet in 1974, restored, and opened to the public in 1976; now used as an interpretive exhibit on the Great South Bay oyster industry at the Long Island Maritime Museum.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:38.644146-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/01001052_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/01001052/c9c2b20c23-800.webp","url_1600":"https://nationalhistoricalregister.com/media/01001052/c9c2b20c23-1600.webp","licence":"CC BY-SA 4.0","author":"Dmadeo","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Rudolph-oyster-house.jpg\" rel=\"noopener\">Dmadeo</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Rudolph-oyster-house.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75316081","wikipedia":"https://en.wikipedia.org/wiki/Rudolph_Oyster_House","wikidata":"https://www.wikidata.org/wiki/Q7377442"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/suffolk-county/rudolph-oyster-house-01001052/"}
