The mill was built for Jacob Steman and his wife Barbara in 1814 and rebuilt for Henry and Anna Withers in 1909.","why_significant":"The nomination argues the complex is significant for commerce, industry, transportation and architecture in Lancaster County history. Milling on the site dates to between 1717 and 1735, and the mill sat at the western terminus of an early trade road. The stone mill is representative of regional stone mills and is one of few surviving mills in Manheim Township, and the adjacent 1868 house and barn make the group the only extant one of its kind there.","narrative":"Along Oregon Road in the Village of Oregon, Manheim Township, stands a limestone mill whose walls date to 1814, when it was built for Jacob Steman and his wife Barbara. The mill was rebuilt in 1909 for Henry and Anna Withers, who raised the roofline, and its paired datestones in English and German record both builds. Milling on or near the site began between 1717 and 1735, and the mill lay at the western end of the Newport-Gap Road, an important trade route between Delaware ports and inland Pennsylvania. Beside the mill are a stone barn built between 1798 and 1815 and a symmetrical Italianate house of 1868, built for Abraham and Eliza Shenk and incorporating walls from an earlier house. Few mills of this type survive in the township, and the grouping of mill, house and barn is the only one of its kind remaining there.","period_of_significance":"1814-1909","architect_builder":null,"architectural_style":"Italianate (house)","criteria":["A","C"],"status_note":"Milling ceased by the late 1940s and the mill subsequently served commercial functions and was vacant for a time.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:33.565494-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/85001389.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/85001389/8ae5bbc80d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/85001389/8ae5bbc80d-1600.webp","licence":"CC BY-SA 4.0","author":"Jerrye &amp; Roy Klotz, MD","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:OREGON_MILL_COMPLEX,_MANHEIM_TWP,_LANCASTER_COUNTY.jpg\" rel=\"noopener\">Jerrye &amp;amp; Roy Klotz, MD</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:OREGON_MILL_COMPLEX,_MANHEIM_TWP,_LANCASTER_COUNTY.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996855","wikipedia":"https://en.wikipedia.org/wiki/Oregon_Mill_Complex","wikidata":"https://www.wikidata.org/wiki/Q7101268"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/oregon-mill-complex-85001389/"}
