Its white wooden verandah against native grey limestone walls made it a landmark that recalls the importance of the base and Lake Champlain in American military history. The nomination marks significance in architecture and military history.","narrative":"Built of random coursed native limestone with ashlar quoins and a water table, this two-story barracks on Plattsburgh Air Force Base dates to 1838-40. A two-story white wooden verandah, twenty-one bays wide, runs across the north front, and several wooden entrance porches serve the south side. It was one of two stone barracks designed as two sides of a hollow square meant to enclose an area 600 feet square. The other building was demolished in 1964, leaving this one as the oldest building on the base. The surrounding military reservation began in 1814 on the shore of Lake Champlain and later hosted many Army infantry regiments and the officer training program known as the Plattsburg Idea. The contrast between the grey stone walls and the white verandah made the building a landmark, and it recalls the part the post and the lake played in American military history.","period_of_significance":"1838-40","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Listed in good condition and altered, on its original site; the form checks military as present use and notes preservation work in progress.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:38.864372-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/71000533.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/71000533/5210d65582-800.webp","url_1600":"https://nationalhistoricalregister.com/media/71000533/5210d65582-1600.webp","licence":"Public domain","author":"SmedleyButler","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:OldStoneBarracks.jpg\" rel=\"noopener\">SmedleyButler</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:OldStoneBarracks.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75316939","wikipedia":"https://en.wikipedia.org/wiki/Old_Stone_Barracks","wikidata":"https://www.wikidata.org/wiki/Q7085100"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/clinton-county/old-stone-barracks-71000533/"}
