Its rubble walls end in large cut stone quoins, and it was originally powered by a wooden overshot wheel. A Rechard turbine, made by the Codorus Iron Works of York, was installed in 1890. The mill ground feed, corn meal and flour with a four-run of stones, and at an early date it also powered a sawmill. Built in 1794, it operated until 1920, when its machinery was scrapped. The mill is regarded as the only surviving mill on Beaver Creek, an area that once had at least three others. Its long service to nearby farms, which chose to mill close to home because of poor roads, is why it is considered significant.","period_of_significance":"1700-1799","architect_builder":"Juhn Nagle","architectural_style":null,"criteria":["A"],"status_note":"Deteriorated roof and altered condition; recent work has included re-roofing, sash and door repair, and re-excavation of the tail race.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.795073-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/80003649.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/80003649/5aaa4989df-800.webp","url_1600":"https://nationalhistoricalregister.com/media/80003649/5aaa4989df-1600.webp","licence":"CC0","author":"Smallbones","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:E_Berlin_Mill_A_from_SE.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:E_Berlin_Mill_A_from_SE.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995758","wikipedia":"https://en.wikipedia.org/wiki/Swigart%27s_Mill","wikidata":"https://www.wikidata.org/wiki/Q16900968"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/york-county/swigarts-mill-80003649/"}
