It was constructed between 1794 and 1798.","why_significant":"The house is significant as an example of the transition from Georgian to Federal architecture and for combining Dutch-German and English building styles in central Pennsylvania. Its asymmetrical facade, floor plan, and interior and exterior woodwork reflect this blend. The nomination notes that the structure has remained remarkably unchanged since construction.","narrative":"Built between 1794 and 1798 by master carpenter Martin Rupp, the fieldstone house in Mechanicsburg was constructed for Johannes Eberly, a wealthy Mennonite farmer from Lancaster County. When finished, it was one of the largest and most elaborate stone houses in the Cumberland Valley. Its two-and-a-half stories, four bays and gabled roof with end chimneys give it an asymmetrical facade, unusual for a house of its period. The three-room ground floor follows a Germanic plan with an axial hall, while the woodwork of the mantels, wall molding and stairway shows the shift from late Georgian to early Federal design. The cornice, six-paneled front door, reeded pilasters and relief carving over the door are original. Rupp also built Peace Church in Cumberland County in 1798-99. The house is valued for blending Dutch-German and English building traditions in central Pennsylvania, and it has changed little since it was built.","period_of_significance":"18th Century","architect_builder":"Martin Rupp (master carpenter)","architectural_style":"Transition from Germanic Pennsylvania farmhouse to Georgian; Georgian to Federal transition","criteria":["C"],"status_note":"The house has remained remarkably unchanged since construction; the original site is retained.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:28.885339-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/73001619.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/73001619/35df3cd755-800.webp","url_1600":"https://nationalhistoricalregister.com/media/73001619/35df3cd755-1600.webp","licence":"CC BY-SA 3.0","author":"Jeremiah Orr","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Johannes_Eberly_House.JPG\" rel=\"noopener\">Jeremiah Orr</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:Johannes_Eberly_House.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996462","wikipedia":"https://en.wikipedia.org/wiki/Johannes_Eberly_House","wikidata":"https://www.wikidata.org/wiki/Q15229638"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/cumberland-county/eberly-johannes-house-73001619/"}
