It includes a circa 1820 Federal-style brick house and a brick mill later converted to a barn, both built by William Helm.","why_significant":"The nomination argues the property is architecturally significant as a rural example of the Federal style and as an unusual Frederick County brick mill converted to a barn. It is historically significant for its role in the county's early milling economy. The mill was also damaged by fire in 1864, likely during the Battle of Opequon, as it stood in the line of battle.","narrative":"Valley Mill Farm lies near the west bank of Abram's Creek, east of Winchester in Frederick County, Virginia. Its centerpiece is a two-story, four-bay Federal-style brick house, built around 1820 by William Helm as the miller's residence. Across Valley Mill Road stands the brick mill, built at about the same time, which was among the more technologically advanced grist and woolen mills in eastern Frederick County. Fire badly damaged the mill in 1864, probably during the Battle of Opequon, and owner William N. Eddy borrowed money to rebuild it. He ran it until about 1875. After 1885 it became a barn, and after 1958 its ground floor served as a veterinary office. The property also holds a tenant house, sheds and two stone ruin sites. It was listed for its Federal architecture and its place in the county's milling economy, with a period of significance of circa 1820 to 1955.","period_of_significance":"circa 1820 - 1955","architect_builder":"William Helm","architectural_style":"Early Republic: Federal","criteria":["A","C"],"status_note":"The farm house is in very good to excellent condition; the barn (former mill) is in fair condition. The farm is in current residential and agricultural use, and two small stone-foundation ruins remain behind the house.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:52:03.40238-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/86/6807/41680786/content/electronic-records/rg-079/NPS_VA/06000032.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/06000032/5dc12a3000-800.webp","url_1600":"https://nationalhistoricalregister.com/media/06000032/5dc12a3000-1600.webp","licence":"CC BY-SA 4.0","author":"AgnosticPreachersKid","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Valley_Mill_Farm_1.JPG\" rel=\"noopener\">AgnosticPreachersKid</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:Valley_Mill_Farm_1.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/41680786","wikipedia":"https://en.wikipedia.org/wiki/Valley_Mill_Farm","wikidata":"https://www.wikidata.org/wiki/Q14713431"},"indexable":true,"url":"https://nationalhistoricalregister.com/virginia/frederick-county/valley-mill-farm-06000032/"}
