It was also the rural seat of the Knickerbocker family, prominent locally for nearly two and a half centuries and involved in colonial and Revolutionary-era military and political life.","narrative":"Knickerbocker Mansion is a brick country house on Knickerbocker Road in Schaghticoke, built by about 1770 by Johannes Knickerbocker II on or beside the site of an earlier family dwelling. It has a rectangular plan, two and a half stories, a hipped roof, five bays across the front, and brick walls on a coursed rubble foundation. A nineteenth-century wood wing stands on the west side, and nineteenth-century details include the porch, the bracketed cornice and the dormer pediments. Inside, the rooms are arranged around a transverse hall. The house is notable as a substantial example of a rural dwelling built by a landed family of some wealth. It is also tied to the Knickerbocker family, whose members served as commanders at Fort Schaghticoke, as militia colonels in the French and Indian War and the Revolution, and as state assemblymen. The family kept the house until 1946. The Knickerbocker Historical Society acquired it in 1964 and ran it as a museum until 1972.","period_of_significance":"18th and 19th centuries","architect_builder":"Johannes Knickerbocker II (completed the dwelling)","architectural_style":null,"criteria":[],"status_note":"Owned by the Knickerbocker Historical Society and open as a museum until 1972, when it was closed for essential repairs; condition listed as fair and altered.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:39.839533-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/72000906.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/72000906/0777a0cc33-800.webp","url_1600":"https://nationalhistoricalregister.com/media/72000906/0777a0cc33-1600.webp","licence":"CC BY 4.0","author":"Peter Flass","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Knickerbocker_Mansion,_Schaghticoke_New_York.jpg\" rel=\"noopener\">Peter Flass</a>, <a href=\"https://creativecommons.org/licenses/by/4.0\" rel=\"license noopener\">CC BY 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Knickerbocker_Mansion,_Schaghticoke_New_York.jpg"},"district":{"nrhp_refnum":"76001274","name":"Champlain Canal","url":"https://nationalhistoricalregister.com/districts/new-york/champlain-canal-76001274/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75321246","wikipedia":"https://en.wikipedia.org/wiki/Knickerbocker_Mansion","wikidata":"https://www.wikidata.org/wiki/Q6422060"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/rensselaer-county/knickerbocker-mansion-72000906/"}
