Its blind-arcaded front with brick pilasters, stepped-gable parapet ends and Adamesque details reflect a townhouse form seldom built outside New York's more cosmopolitan communities. It was also considered in the late nineteenth century to be the finest brick house in the county.","narrative":"Built in 1816 for Johnstown attorney Benjamin Chamberlain, this brick townhouse stands on the corner of South Market and Clinton Streets, two blocks from the county courthouse. The house rises two and a half stories above a fieldstone foundation under a standing-seam metal roof. Its west front is divided into three bays by a blind arcade of rounded arches on brick pilasters, and stepped parapet gables with four tall chimneys mark the end walls. Elliptical attic windows hold the only original sash. A two-story rear wing once housed servants. Inside, the side-hall plan survives, along with the original staircase, baseboards, window casings and a molded mantel in the front parlor. Chamberlain sold the house in 1832 to lawyer John Frothingham, whose family kept it until 1875. The house is valued as a rare Federal townhouse in a frontier county seat, a form more common in larger New York communities, and was once called the finest brick house in the county.","period_of_significance":"1816","architect_builder":null,"architectural_style":"Early Republic/Federal","criteria":["C"],"status_note":"Historic and current function is single-family dwelling; interior and sash were altered in the late nineteenth and early twentieth centuries, but the form retains considerable integrity.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:51.348711-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/99000989.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/99000989/4b15338237-800.webp","url_1600":"https://nationalhistoricalregister.com/media/99000989/4b15338237-1600.webp","licence":"CC BY-SA 2.0","author":"Doug Kerr from Upstate New York","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Chamberlain_Benjamin_House_Feb_08.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:Chamberlain_Benjamin_House_Feb_08.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75317846","wikipedia":"https://en.wikipedia.org/wiki/Benjamin_Chamberlain_House","wikidata":"https://www.wikidata.org/wiki/Q4888383"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/fulton-county/chamberlain-benjamin-house-99000989/"}
