The house was built in 1788.","why_significant":"The nomination argues the house is a locally significant example of 18th century German vernacular domestic architecture that incorporates English Georgian elements such as the center hall, double pile plan, and flat arches. It cites German construction features including the date stone, queen post roof truss, vaulted cellar, and bi-colored mortar, and states that it is one of few surviving pre-1800 buildings in the county with such German vernacular elements.","narrative":"Built in 1788 of local grey limestone by Conrad Alleman, a German-born farmer, this two and a half story house in Lower Swatara Township, Dauphin County, combines German building traditions with English Georgian details. A date stone in the east gable reads \"Built C A 1788,\" and the house has a center hall, double pile plan, a vaulted brick cellar, and a queen post roof truss known as a stehender stuhl. Flat arches of red sandstone and limestone keystones sit over the first floor openings, and the mortar is colored with crushed red sandstone. A c.1800 east wing added a two-story wood porch. The Alleman family owned the property from 1788 until 1978. The house is regarded as a significant surviving example of Pennsylvania German vernacular architecture in the county, showing how families of modest means adopted English styles while keeping German construction methods. Its high degree of integrity in structure and interior details is cited as a key reason for its significance.","period_of_significance":"1788-c.1800","architect_builder":null,"architectural_style":"Colonial: Georgian; German vernacular","criteria":["C"],"status_note":"The document states that the house has a high degree of integrity; a terraced patio was built in 2009 and the original barn collapsed in 1984.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:10:27.312789-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/11000644.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/11000644/cd8ba789b8-800.webp","url_1600":"https://nationalhistoricalregister.com/media/11000644/cd8ba789b8-1600.webp","licence":"CC BY-SA 4.0","author":"JERRYE &amp; ROY KLOTZ, M.D.","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:CONRAD_AND_MARGARET_ALLERMAN_HOUSE,_DAUPHIN_COUNTY,_PA.jpg\" rel=\"noopener\">JERRYE &amp;amp; ROY KLOTZ, M.D.</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:CONRAD_AND_MARGARET_ALLERMAN_HOUSE,_DAUPHIN_COUNTY,_PA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995403","wikipedia":"https://en.wikipedia.org/wiki/Conrad_and_Margaret_Allerman_House","wikidata":"https://www.wikidata.org/wiki/Q5162639"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/dauphin-county/allerman-conrad-and-margaret-house-11000644/"}
