It is a vernacular mill structure of the eastern Pennsylvania type.","why_significant":"The nomination argues the mill is typical of early nineteenth-century grist mills in eastern Pennsylvania and that it stands on the site of an 18th-century iron furnace linked to the Revolutionary War. It also cites associations with signer George Taylor, General Daniel Morgan, and the Durham boats, and its operation as a mill until 1967.","narrative":"Durham Mill is a three-story stone grist mill in Durham, Bucks County, Pennsylvania, built in 1820 on the foundation walls of the Durham Furnace, an iron works dating from 1727. The mill follows the layout of a standard early nineteenth-century eastern Pennsylvania grist mill, with an overshot waterwheel fed by a three-quarter-mile raceway from Cook's Creek. The furnace produced pig and bar iron, cast iron wares, and during the Revolution, cannon, shot and other equipment for colonial troops. Durham boats built in the area were used in Washington's crossing of the Delaware. Rubin Knecht Bachman, a U.S. Representative, owned the mill in the late nineteenth and early twentieth centuries and added a brick warehouse in 1912. The mill operated continuously until 1967, mainly producing livestock feed. The county now owns it and is restoring the exterior.","period_of_significance":"1820-1967","architect_builder":null,"architectural_style":"Vernacular","criteria":["A","C"],"status_note":"Exterior restoration under way; interior restoration and future operation as a living history museum are planned; open to the public May through October.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:29.190189-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/76001608.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/76001608/67c9937b6e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/76001608/67c9937b6e-1600.webp","licence":"CC BY-SA 3.0","author":"Shuvaev","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Durham_Mill_PA_01.JPG\" rel=\"noopener\">Shuvaev</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:Durham_Mill_PA_01.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71995307","wikipedia":"https://en.wikipedia.org/wiki/Durham_Mill_and_Furnace","wikidata":"https://www.wikidata.org/wiki/Q5316533"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bucks-county/durham-mill-and-furnace-76001608/"}
