It was built by Jacob Ulery in 1835.","why_significant":"The nomination argues the mill is significant as the only surviving one of several mills built along Tenmile Creek in the early 1830s, and as an example of an early gristmill that served the local farming community. Its water-powered operation was later converted to steam by Stephen Ulery.","narrative":"Built in 1835 by Jacob Ulery on Tenmile Creek in the village of Zollarville, this two-and-a-half-story brick gristmill rests on a stone foundation designed to bear the weight and motion of grinding stones. It was originally powered by a water wheel. Stephen Ulery, who inherited it, converted the mill to steam power and laid out the streets of the growing town in 1865. The mill was later operated by William Pollock until the early 1920s, then used by a later owner as a grocery store and butcher shop until 1963. Central loading doors on all three stories once carried grain into upper storage floors. The building is plain, with two-over-two sash windows and no exterior decoration. Its interest lies in being the only surviving one of several mills built along the creek in the early 1830s, and in its role grinding flour and meal for local markets and families. Its machinery has been removed, though an old millstone remains in the basement.","period_of_significance":"1835","architect_builder":"Jacob Ulery (builder)","architectural_style":null,"criteria":[],"status_note":"The document states the mill is currently rented and used as an antique store; the mill is described as in good condition.","vacant_flag":false,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:30.732673-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/78002481.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/78002481/36f69d86fe-800.webp","url_1600":"https://nationalhistoricalregister.com/media/78002481/36f69d86fe-1600.webp","licence":"CC BY-SA 3.0","author":"Generic1139","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Ulery_Mill.jpg\" rel=\"noopener\">Generic1139</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:Ulery_Mill.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71996378","wikipedia":"https://en.wikipedia.org/wiki/Ulery_Mill","wikidata":"https://www.wikidata.org/wiki/Q16902265"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/washington-county/ulery-mill-78002481/"}
