Two two-story stone buildings so close together are described as atypical for the region. It is also valued for its cohesive agrarian setting and ties to the southwestern Ohio wine industry.","narrative":"Weedy Valley Farm, formally the Roas-Ilhardt Farm and Winery, occupies a secluded valley in Pierce Township, Clermont County. The complex centers on a two-story, five-bay farmhouse of local surface limestone with massive stone lintels and chiseled cornerstones, plus a stone winery built into a hillside behind it. A springhouse, smokehouse, blacksmith shop, cattle barn and stone wall complete the setting. Inside the house, walnut chairrails, Federal style mantels, paneled cupboards and a cherry and walnut balustrade show careful craftsmanship. Matthias Roas, a German immigrant, bought the property in 1850 and made improvements. The Ilhardt family acquired it in 1869 and later supplied wine to a Cincinnati hotel. The farm was listed for its link to early German settlement, its unusual pair of two-story stone buildings, its stone vernacular architecture, its intact agricultural setting and its place in the region's wine history. A circa 1950 frame wing is the main alteration.","period_of_significance":"c. 1849-1850","architect_builder":"Matthias Roas","architectural_style":"Nineteenth century stone vernacular architecture with Federal style features","criteria":[],"status_note":"Described as in excellent condition, occupied and used as a private residence; the farmhouse was altered by a frame wing added circa 1950 and the winery is being renovated and extended.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:12.02793-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/82003553.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82003553/71245a92f4-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82003553/71245a92f4-1600.webp","licence":"CC BY-SA 3.0","author":"Aesopposea","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Roas-IlhardtFarmAndWinery.JPG\" rel=\"noopener\">Aesopposea</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:Roas-IlhardtFarmAndWinery.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71987122","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q137608248"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/clermont-county/roas-ilhardt-farm-and-winery-82003553/"}
