The first section was built about 1825, with additions through the early 20th century.","why_significant":"The nomination argues the mill is significant for its role in the local milling industry, operating as a gristmill from about 1825 until the late 1960s and later as a feed mill. It is also presented as an excellent example of mill architecture, with its original machinery largely intact and its plain Georgian-style features reflecting its function.","narrative":"Beside the Tohickon Creek on Covered Bridge Road in East Rockhill Township, Bucks County, stands a three-story stone mill whose first section dates to about 1825. Built of randomly laid fieldstone with a milled timber frame, it grew through additions around 1850, about 1870 and about 1905, the last housing a cider press. A millrace and stone-lined forebay feed water to the building, and its interior still holds much of its historic machinery, including a flour dresser, scourers, a hammermill and drive belts. The mill is regarded as an excellent example of mill architecture and has an important role in local milling history. It ground grain and produced feed until the late 1960s, and in 1917 new Robinson Manufacturing equipment was installed. Its records also show a later contract to sell Purina feed. Its surviving machinery and building fabric document the shift from water-powered milling to commercial feed production.","period_of_significance":"c.1825 to C. 1917","architect_builder":null,"architectural_style":"Colonial Period, Georgian style features","criteria":["A","C"],"status_note":"Operated as a gristmill until the late 1960s; cider press operated until 1980; the mill property later became part of a campground.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:10:27.307248-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/06001149.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/06001149/cced869701-800.webp","url_1600":"https://nationalhistoricalregister.com/media/06001149/cced869701-1600.webp","licence":"CC BY-SA 3.0","author":"PattiParker","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Levi_Sheard_Grist_Mill.JPG\" rel=\"noopener\">PattiParker</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:Levi_Sheard_Grist_Mill.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71997904","wikipedia":"https://en.wikipedia.org/wiki/Levi_Sheard_Mill","wikidata":"https://www.wikidata.org/wiki/Q6535514"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/bucks-county/sheard-levi-mill-06001149/"}
