Agoston Haraszthy built them in 1862-1864 at the Buena Vista Vinicultural Society.","why_significant":"The buildings are tied to Agoston Haraszthy's effort to build a large, modern wine-producing complex at Buena Vista, an early and influential venture in California winemaking. Contemporary accounts and photographs treated the structures as models for the industry. They also illustrate 19th-century California agricultural and commercial practices, and they remain in winery use.","narrative":"Near the city of Sonoma, two stone buildings built in the early 1860s recall the start of large-scale winemaking in California. The Press House, finished in 1862 or 1863, and the Main Winery, completed in July 1864, were designed by Agoston Haraszthy and built of locally quarried stone. Their plain, symmetrical forms have gabled roofs, and stone quoins mark the arches, doors and windows. Both front on tunnels cut into a hillside to age wine at steady temperatures. The buildings were once at the center of the Buena Vista Vinicultural Society, which held nearly 6,000 acres and planned products from wine and brandy to lime and building stone. Haraszthy followed construction advice he had published in the 1850s, and contemporary accounts presented the complex as a model for the industry. Earthquake repairs, a concrete lintel, and a 1982 interior rebuilding altered the structures, yet both still serve the winery for which they were built.","period_of_significance":"1862-1864","architect_builder":"Agoston Haraszthy","architectural_style":"Vernacular, reminiscent of north central Europe","criteria":[],"status_note":"Both buildings remain part of the operating Buena Vista Winery. The Press House was renovated in 1982 for public use, and the Main Winery stores large casks of wine.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:27.909139-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/86001902.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/86001902/ae03398f1e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/86001902/ae03398f1e-1600.webp","licence":"Public domain","author":"Matkatamiba","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Buena_Vista_Winery,_Sonoma,_CA.jpg\" rel=\"noopener\">Matkatamiba</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Buena_Vista_Winery,_Sonoma,_CA.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123862042","wikipedia":"https://en.wikipedia.org/wiki/Buena_Vista_Winery","wikidata":"https://www.wikidata.org/wiki/Q49226"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/sonoma-county/buena-vista-vineyards-buena-vista-vinicultural-society-86001902/"}
