It retains outstanding integrity. It is also tied to the Wynkoop and Lounsbery families, and George Washington dined and lodged there in November 1782.","narrative":"Built in 1767 for merchant Cornelius Wynkoop, this stone house sits on a narrow ridge along Main Street in Stone Ridge, a hamlet of Marbletown in Ulster County. The main block is two full stories with a high attic under a gambrel roof, built of local gray limestone, with a cut-stone five-bay front, a modillioned cornice and a center-hall plan. A kitchen ell extends to the rear, and a wagon shed of about the same date remains on the thirteen-acre property, along with a row of six black locusts planted in the house's early years. The house is regarded as one of only two large gambrel-roofed stone houses in New York designed in that form from the outset, blending Georgian symmetry with Dutch proportions and construction. Inside, wide pine floors, whitewashed walls, paneled chimney breasts and eighteenth-century Delft tiles survive. George Washington dined and lodged here in 1782, and the Wynkoop and Lounsbery families, prominent in the region, owned it through the early nineteenth century.","period_of_significance":"ca.1767-ca.1850","architect_builder":null,"architectural_style":"Colonial/Georgian (Dutch Colonial gambrel-roofed stone house)","criteria":["A","B","C"],"status_note":"Historic and current use is single dwelling with a secondary structure (wagon shed); the house retains much original fabric, with a restored wagon shed.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:51.559013-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/96000138.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/96000138/20d895bf6d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/96000138/20d895bf6d-1600.webp","licence":"CC BY-SA 3.0","author":"Daniel Case","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Wynkoop_Stone_House.jpg\" rel=\"noopener\">Daniel Case</a>, <a href=\"http://creativecommons.org/licenses/by-sa/3.0/\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Wynkoop_Stone_House.jpg"},"district":{"nrhp_refnum":"88000666","name":"Main Street Historic District","url":"https://nationalhistoricalregister.com/districts/new-york/main-street-historic-district-88000666/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75322765","wikipedia":"https://en.wikipedia.org/wiki/Cornelius_Wynkoop_Stone_House","wikidata":"https://www.wikidata.org/wiki/Q5171478"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/ulster-county/wynkoop-cornelius-stone-house-96000138/"}
