The original five-bay section measures 43' by 25' with a four-bay north addition.","why_significant":"The house is significant for its architecture as a well preserved example of early vernacular architecture of the Cumberland Valley, built of local fieldstone in a five-bay center hall plan. It is also associated with the early iron industry in Franklin County through the nearby Mt. Pleasant Iron Works, opened in 1783.","narrative":"Built of coursed local fieldstone on a gentle slope in Path Valley, this two-story house near Richmond Furnace in Metal Township has a five-bay original section measuring 43 by 25 feet and a four-bay addition on its north gable end. Its facade has flat arches over first-story openings, a segmental stone arch over the south cellar entrance, and six-over-nine and six-over-six double-hung sashes set in pegged wooden frames. The interior is organized around a central hall with plain woodwork and chair rails. The house is regarded as a well preserved example of early vernacular architecture in the Cumberland Valley, representing a major architectural group in Pennsylvania and the Cumberland and Shenandoah Valleys. Its construction is placed after 1798, with the north addition dated to the second quarter of the nineteenth century. The property is also tied to the early iron industry, as the nearby Mt. Pleasant Iron Works opened in 1783 under George Chambers, on land first owned by Col. Benjamin Chambers.","period_of_significance":"19th Century (early)","architect_builder":null,"architectural_style":"Early vernacular architecture of the Cumberland Valley; five-bay center hall plan","criteria":[],"status_note":"The house is in excellent condition and is being refurbished by the present owners with an effort at restoration.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.436092-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/74001785.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/74001785/9128491396-800.webp","url_1600":"https://nationalhistoricalregister.com/media/74001785/9128491396-1600.webp","licence":"CC BY-SA 3.0","author":"Cromdog","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Mt._Pleasant_Iron_Works_House.JPG\" rel=\"noopener\">Cromdog</a>, <a href=\"https://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:Mt._Pleasant_Iron_Works_House.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995598","wikipedia":"https://en.wikipedia.org/wiki/Mt._Pleasant_Iron_Works_House","wikidata":"https://www.wikidata.org/wiki/Q15260152"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/franklin-county/mt-pleasant-iron-works-house-74001785/"}
