Route 23 in Roxbury, Delaware County, New York, centered on a stone bank house built about 1790 with a frame addition of about 1820, plus outbuildings, ruins and fields on roughly 30 acres.","why_significant":"The nomination argues the house is tied to the expansion and decline of New York's early land patents (Criterion A). It also presents the house as an intact, representative example of late eighteenth-century vernacular stone architecture (Criterion C), blending Georgian and Dutch/German building traditions. The house was home to Roxbury's first Town Supervisor and housed the area's first store.","narrative":"Set on Route 23 in the Catskill region, this Roxbury farm centers on a stone house built about 1790 by Isaac Hardenbergh, grandson of Johannes Hardenbergh, whose 1708 patent covered much of the Catskills. The house is built as a bank house, three stories at the south and two at the north, with a five-bay symmetrical front, brick quoining and Georgian proportions. Its central chimney, boxed stairs and exposed floor joists reflect Dutch and German building habits. A frame addition of about 1820 stands to the north. Hardenbergh ran an early mill and the area's first store, and served as Roxbury's first town supervisor from 1799 to 1806. Later generations farmed, turned to dairying, and in the early twentieth century operated a tourist home. The 30-acre property also holds a stone smokehouse, dug well, carriage barn, barn and tenant house ruins, and cobblestone gateposts set with millstones. Its period of significance runs from about 1790 to 1933.","period_of_significance":"ca. 1790-1933","architect_builder":null,"architectural_style":"Colonial / Georgian","criteria":["A","C"],"status_note":"Current owners have maintained the house without significant alterations since 1969; the property remains a single dwelling with secondary structures and agricultural fields.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:51:50.095882-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/94001369.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75317227","wikipedia":"https://en.wikipedia.org/wiki/Isaac_Hardenbergh_House","wikidata":"https://www.wikidata.org/wiki/Q6076449"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/delaware-county/hardenbergh-isaac-house-94001369/"}
