It represents the country seats built by wealthy landlords in upstate New York after the Revolution and reflects the Duane family's prominence. Its Federal style frame barns are described as exceptionally rare survivors in the state.","narrative":"Set on a wooded hilltop above the town of Duanesburg, this two-story frame mansion was built between about 1812 and 1816 by Catharine Livingston Duane, daughter of the town's founder, James Duane. It has a low hipped roof, a two-story piazza with massive Doric columns on the north side, and slender Ionic entrance porches. The interior retains much tiger maple woodwork and the original basement kitchen. Five nineteenth-century outbuildings survive, including a Federal style carriage barn and a hay barn. The design is considered an unusual rural take on Federal architecture, with elongated porches and an arcade of windows opening onto the portico. The architect is unknown, though Philip Hooker has been suggested, and Jacques Ramee designed the lost formal gardens. Catharine Duane was known for charity, including a public lending library in the house. The property has stayed in the Featherstonhaugh family for seven generations.","period_of_significance":null,"architect_builder":"Architect unknown; landscape architect Jacques Ramee; builder Solomon Kelly, Princetown","architectural_style":"Federal (Adamesque vocabulary)","criteria":[],"status_note":"Described as a private residence in good condition, still in the Featherstonhaugh family, with no known threats. A tornado in 1882 swept away the original columns, and a kitchen was added on the main floor in the 1940s.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:45.114372-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/87000910.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/87000910/ea15412f1c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/87000910/ea15412f1c-1600.webp","licence":"CC BY-SA 2.0","author":"Schenectady County","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Duane_Mansion_Sep_09.jpg\" rel=\"noopener\">Schenectady County</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:Duane_Mansion_Sep_09.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75314550","wikipedia":"https://en.wikipedia.org/wiki/Duane_Mansion","wikidata":"https://www.wikidata.org/wiki/Q5310363"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/schenectady-county/duane-mansion-87000910/"}
