Original 19th-century equipment, including a primitive lever press, remains on site. Its stone winery with residence above reflects the European heritage of Swiss-born builder Anton Nichelini and of the immigrants who shaped the local wine industry.","narrative":"Built in 1890 by Swiss-born Anton Nichelini, this three-story winery and residence is cut into a steep hillside east of Sage Canyon Road near St. Helena. The ground level is native cut stone and served as the wine cellar, with a segmental-arched central door and corner quoins. The upper two floors, finished by 1896, are frame with board-and-batten and horizontal siding and housed the Nichelini family. A frame barn/winery building stands to the north. Nichelini homesteaded the land in 1884, planted vineyards, developed small mines, and sold wine to workers in nearby quicksilver mines. The winery closed during Prohibition and was reopened after Repeal by his son William, and it has stayed small and family-run. Nineteenth-century equipment, including a primitive lever press, remains in place. It was listed as an example of the owner-built family winery typical of late 19th-century Napa County and of the European immigrant influence on the local wine industry and stonework.","period_of_significance":"1800-1899","architect_builder":"Anton Nichelini","architectural_style":"Vernacular, with Greek Revival suggestions in the cornice returns","criteria":[],"status_note":"Occupied and still in operation as a small, family-run winery; the design is described as unaltered.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.823842-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/79000508.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79000508/7c264eab02-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79000508/7c264eab02-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Nichelini_Winery,_2950_Sage_Canyon_Rd,_St._Helena,_CA_10-22-2011_5-52-56_PM.JPG\" rel=\"noopener\">Sanfranman59</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:Nichelini_Winery,_2950_Sage_Canyon_Rd,_St._Helena,_CA_10-22-2011_5-52-56_PM.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123860066","wikipedia":"https://en.wikipedia.org/wiki/Nichelini_Family_Winery","wikidata":"https://www.wikidata.org/wiki/Q18753759"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/napa-county/nichelini-winery-79000508/"}
