It opened commercially in 1933 after Prohibition ended and expanded during the World War II era with a large winery built in 1947-1949. It is significant locally under Criterion A in agriculture and commerce.","narrative":"Galleano Winery is a cluster of agricultural buildings divided by two-lane Wineville Road in Mira Loma, in the Cucamonga Valley of western Riverside County. The nominated area covers about 1.8 acres and includes a barn, original winery, bunkhouse/office, guesthouse, vinegar shed, garage and a large concrete block main winery built in 1947-1949. The earliest structures date to about 1900, and the family adapted a barn or shed for wine production. The Galleano family bought the land in 1927 and opened a commercial winery in 1933, after Prohibition ended. Under Nino Galleano the business expanded onto the west side of the road in the 1940s. The complex is valued as a rare survivor of a once widespread valley industry that peaked in the 1940s, when more than sixty wineries operated. Winemaking and retail sales continue on the site today, run by the third generation of the family.","period_of_significance":"1933-1953","architect_builder":null,"architectural_style":"No style","criteria":["A"],"status_note":"Still operating as a winery with retail tasting room and sales; the bunkhouse/office was recently rehabilitated as the winery office.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:26.902938-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/03000533.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123860468","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q141641505"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/riverside-county/galleano-winery-03000533/"}
