It is significant under Criterion C as the work of prominent local architect Isaac Green, Jr., and as a rare public building he designed in the Shingle style.","narrative":"Built in 1888 at 131 Middle Road in Sayville, on Long Island's Great South Bay, this Congregational church is a Shingle style building with two prominent towers and fish-scale shingles that curve over arches and windows like waves. Architect Isaac Green, Jr. designed it from preliminary sketches by Robert Nunns, a local builder and church member who insisted on quarter-sawn oak woodwork. Inside, an auditorium-style sanctuary has raked seating, a barrel-vaulted ceiling with exposed trusswork, and a chancel that was expanded in 1956. The congregation, organized in 1858, grew quickly after a successful revival under Reverend Thomas Douglas, and the church was dedicated in 1890. It matters as one of Sayville's earliest churches serving a population drawn to maritime work, and as a rare public building by Green in the Shingle style. A parsonage and a 1955 education building on the site are non-contributing.","period_of_significance":"1888-1955","architect_builder":"Isaac Green, Jr.; Robert Nunns","architectural_style":"Shingle Style","criteria":["A","C"],"status_note":"Still in use as a church (Sayville Congregational United Church of Christ); the worship space is described as largely intact.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:53.231337-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/05000747.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/05000747/ed7e2fe1f5-800.webp","url_1600":"https://nationalhistoricalregister.com/media/05000747/ed7e2fe1f5-1600.webp","licence":"CC BY-SA 2.0","author":"Doug Kerr from Upstate New York","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Sayville_Congregational_Church_Mar_10.jpg\" rel=\"noopener\">Doug Kerr from Upstate New York</a>, <a href=\"https://creativecommons.org/licenses/by-sa/2.0\" rel=\"license noopener\">CC BY-SA 2.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Sayville_Congregational_Church_Mar_10.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75314995","wikipedia":"https://en.wikipedia.org/wiki/Sayville_Congregational_Church","wikidata":"https://www.wikidata.org/wiki/Q7429324"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/suffolk-county/sayville-congregational-church-05000747/"}
