It is the only surviving structure of the forge site.","why_significant":"The house is regarded as an excellent example of rural Georgian architecture and an early pre-Revolutionary ironmaster's residence. Its stonework, original interior panelling and detailing, and plan show the standard of living of iron masters before the Revolution. The forge itself was one of the early iron works on French Creek that supplied iron during the period of independence.","narrative":"Built of coursed native fieldstone on a southern slope near French Creek, this two and one-half story house with a gable roof and wide center hall was probably completed by John and Susanna Young shortly after they took title to the forge property in 1770. It served first as an ironmaster's home and office, with the first floor used for forge business and the upper floors for family living. Its stonework was hidden under stucco from the 1850s until the covering was removed in 1981. The interior retains original Georgian chimney breast panelling, cove moldings, corner cupboards and a Queen Anne curved fireplace, and its details resemble those of other wealthy ironmasters' houses on French Creek. The house is the last surviving structure of the Vincent Forge, which operated from about 1760 to 1800, and is valued for its early date, fine masonry and largely intact interior.","period_of_significance":"circa 1770","architect_builder":null,"architectural_style":"Georgian (rural Georgian, full country Georgian style)","criteria":[],"status_note":"Restored from a later stucco covering and dining hall removal in 1981; the document describes an ongoing restoration.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.58824-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/85001003.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85001003/564965eb2a-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85001003/564965eb2a-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Kerry_Dell_Farm.JPG\" rel=\"noopener\">Smallbones</a>, <a href=\"http://creativecommons.org/publicdomain/zero/1.0/deed.en\" rel=\"license noopener\">CC0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Kerry_Dell_Farm.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998210","wikipedia":"https://en.wikipedia.org/wiki/Vincent_Forge_Mansion","wikidata":"https://www.wikidata.org/wiki/Q7931797"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/chester-county/vincent-forge-mansion-85001003/"}
