The buildings date from 1840 to 1908 and include a Baptist church, parsonage and carriage barn, a grange hall, and a schoolhouse with a coal shed/privy.","why_significant":"The district is argued to be architecturally significant as a well-preserved group of nineteenth-century public and semi-public buildings reflecting national trends and styles in a rural North Country hamlet. The 1870s buildings, including the Akron-plan church wing, the grange hall and the four-room school, introduced new building types to Lyme. The buildings are also historically significant for their central role in the civic life of Three Mile Bay.","narrative":"Along the curving Depot Street in Three Mile Bay, a hamlet in the town of Lyme, stand six buildings built between 1840 and 1908 for public and semi-public use. They include a Greek Revival Baptist church of 1840, its 1844 parsonage rebuilt in 1908, a carriage barn, a grange hall of about 1874, and a four-room Italianate schoolhouse of 1878 with its coal shed and privy. Depot Street was laid out around 1852 to link the harbor with a railroad depot, and it became the center of civic life. The district matters for architecture and community history. In 1874 the church added a Sunday School wing following the Akron plan, along with a Gothic-style steeple, while the grange hall and the school brought new building types to Lyme during a period of farm prosperity. The wood-frame buildings, set on limestone foundations, stand larger than the surrounding cottages and remain well preserved.","period_of_significance":"1840-1908","architect_builder":null,"architectural_style":"Greek Revival vernacular; Italianate palazzo style","criteria":["C"],"status_note":"Some buildings have alterations: the grange hall has boarded ground-floor windows, and the school's first-floor classroom was converted to residential use in the 1980s.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:45.709005-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/90001327.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75313160","wikipedia":"https://en.wikipedia.org/wiki/Three_Mile_Bay_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q7797631"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/jefferson-county/three-mile-bay-historic-district-90001327/"}
