It was built around 1793 on the foundation of an earlier Van Tassel house.","why_significant":"The house is a rare surviving late eighteenth century stone dwelling in Greenburgh and reflects the region's vernacular stone building tradition. It is tied to Cornelius Van Tassel and John Romer, two prominent local figures. It also served as Greenburgh's first town hall from 1793 into the early nineteenth century.","narrative":"This stone house on Saw Mill River Road, just south of Elmsford in Greenburgh, was built around 1793 on the foundation of an earlier Van Tassel home burned by British troops in 1777. John Romer, who married Leah Van Tassel, and her father Cornelius Van Tassel began the new house, and it later served as Greenburgh's first town hall. Romer was a Revolutionary War veteran who also served in the War of 1812 and died in 1855. The one-and-one-half story building has a gable roof, gable-end chimneys, a center entrance, wood-framed gables and massive stone fireplaces. A date stone reads 1793, and a stone inside the east fireplace is inscribed 1684. The 1920s renovation rebuilt a wing, added a kitchen wing and a dormer, and changed some windows, but the layout and character remain largely intact. The four-acre property also holds a modern garage and swimming pool, which do not contribute to its significance.","period_of_significance":"ca. 1793 - 1855","architect_builder":null,"architectural_style":"Colonial","criteria":["A","B","C"],"status_note":"Currently used as a single dwelling; a 1920s renovation altered parts of the exterior and interior, but the form states the house retains sufficient integrity.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:50.955429-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/94001373.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/94001373/1ffd0eae1d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/94001373/1ffd0eae1d-1600.webp","licence":"CC BY-SA 4.0","author":"Magicpiano","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:GreenburghNY_RomerVanTasselHouse.jpg\" rel=\"noopener\">Magicpiano</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:GreenburghNY_RomerVanTasselHouse.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75323195","wikipedia":"https://en.wikipedia.org/wiki/Romer-Van_Tassel_House","wikidata":"https://www.wikidata.org/wiki/Q7363151"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/westchester-county/romer-van-tassel-house-94001373/"}
