The site has never been systematically excavated and could yield evidence on illicit wartime trade across the northern frontier, such as British coin or goods found at the fort.","narrative":"Fort Brown is the surviving earthwork of a fort built in the summer of 1814 on a wedge-shaped parcel of about 2.85 acres beside a sharp bend in the Saranac River in Plattsburgh, New York. Major General George Izard had it raised as one of three forts across the southern land approach to Plattsburgh, as British forces threatened from Lake Champlain. It was the westernmost of the redoubts, with Forts Moreau and Scott to its east. An 1815 map shows it as an irregular five-sided earthwork with small bastions and gun emplacements. The other works were later leveled, but this parcel fell into disuse and is now owned by the city and maintained in a natural state. No systematic excavation has taken place, though informal probing has left depressions. The site is considered important for its link to the Battle of Plattsburgh of September 1814 and for its research potential, particularly on illicit trade with British forces in Canada during the War of 1812.","period_of_significance":"1800-1899","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"City-owned and kept in a natural, undeveloped state as a historic monument; remains are ruins, and unrecorded probing has occurred with unknown effect on integrity.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:39.092924-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/78001846.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75316926","wikipedia":"https://en.wikipedia.org/wiki/Fort_Brown_Site","wikidata":"https://www.wikidata.org/wiki/Q5470860"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/clinton-county/fort-brown-site-78001846/"}
