Construction began in 1806 and was finished by about 1818.","why_significant":"It is an intact example of vernacular Federal masonry architecture in Lyme, with ornament such as paired gable-end chimneys, ovoid gable windows and elliptical-arched fanlit entrances. It is also tied to James LeRay de Chaumont, the French landowner who began settling Jefferson County; the building served as his land office, guest house and Lyme's first public inn. Later it became one of the town's first seasonal homes.","narrative":"Chaumont House is a stone residence at the corner of Water Street and Main Street in the village of Chaumont, Jefferson County. Begun in 1806 for James LeRay de Chaumont, the French landowner who promoted settlement across northern Jefferson County, it combined a land office, lodging for LeRay and his guests, and later a public inn. His agent Musgrove Evans finished it by 1818. The main block is a five-by-three-bay Federal building of roughly dressed limestone, set off by paired gable-end chimneys, ovoid gable windows, smooth limestone trim and elliptical-arched entrances with fanlights. A frame wing was altered in 1929. After the railroad shifted the village center, the building declined, then was revived in the 1890s as a summer home with Colonial Revival porches. Its original central-hall plan and mantelpieces survive. A carriage barn and 1920s garage also contribute. The house is regarded as one of the oldest buildings in Lyme and its most intact stone building of this type.","period_of_significance":"c.1806-1820","architect_builder":null,"architectural_style":"Vernacular Federal","criteria":["A","B","C"],"status_note":"Condition listed as good; still used as a residence, with a contributing carriage barn and garage and a non-contributing pool and poolhouse.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:45.983631-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/90001341.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75313234","wikipedia":"https://en.wikipedia.org/wiki/Chaumont_House","wikidata":"https://www.wikidata.org/wiki/Q5088190"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/jefferson-county/chaumont-house-90001341/"}
