It includes a stone residence dated c. 1840, a stone Pennsylvania bank barn, a c. 1790 stone springhouse, and several c. 1940s agricultural buildings on about 108 acres.","why_significant":"The nomination argues the farm is significant for its association with Montgomery County and southeastern Pennsylvania agriculture, and for its Georgian double-cell residence and Pennsylvania bank barn under architectural criteria. It also cites the springhouse and early tax records as indicating potential for historic archaeology, since an earlier 1790s dwelling stood on the property.","narrative":"Located at the crossroads of Dekalb Pike and Welsh Road in Upper Gwynedd Township, the farm holds a stone residence built around 1840, a stone Pennsylvania bank barn, and a springhouse dating to about 1790. The residence is a two-story, side-gabled building in a simple Georgian style, with a central double-cell core and later stone and concrete block additions. The barn retains its stone construction and banked entrance. The farm is regarded as an example of a mid-nineteenth-century Montgomery County farmstead, with about 108 acres of cropland and woodland still surrounding the complex. Its significance lies in its architecture, its agricultural history, and its archaeological potential. Tax records point to an earlier wooden dwelling on the site from the 1790s, and the springhouse may have served that house. The property was used for dairy and grain farming through the nineteenth century, with production shifting toward dairy and hay after railroad access opened the Philadelphia market.","period_of_significance":"c1790 1949","architect_builder":null,"architectural_style":"Colonial/Georgian","criteria":["A","C","D"],"status_note":"Contributing resources include the residence, barn, springhouse, and three agricultural support buildings; a modern metal storage building does not contribute.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:35.716948-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/00001346.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/00001346/077341a64f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/00001346/077341a64f-1600.webp","licence":"CC BY-SA 3.0","author":"JERRYE &amp; ROY KLOTZ MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:KNIPE-JOHNSON_FARM.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ MD</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:KNIPE-JOHNSON_FARM.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71998444","wikipedia":"https://en.wikipedia.org/wiki/Knipe%E2%80%93Johnson_Farm","wikidata":"https://www.wikidata.org/wiki/Q15238669"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/montgomery-county/knipe-johnson-farm-00001346/"}
