Its headquarters centers on the Ygnacio del Valle Adobe, begun about 1853, with a winery, chapel, and railroad-related buildings.","why_significant":"The ranch is tied to the Del Valle family's rancho and agricultural history, including its wine and citrus production. It is also strongly linked to Helen Hunt Jackson's novel Ramona, which made it a tourist destination after the railroad arrived in 1887. It retains a largely intact citrus landscape and historic building plan.","narrative":"Rancho Camulos is an 1,800-acre citrus ranch in the Santa Clara River Valley near Piru, Ventura County. Its headquarters is anchored by the Ygnacio del Valle Adobe, begun around 1853 and expanded in phases into a U-shaped plan by the early twentieth century. Nearby are a brick winery built in 1867, a small wooden chapel, a bell structure, a brick fountain, and later Craftsman and Spanish Colonial Revival buildings. Across the highway stand railroad-related houses from 1887 and farm labor cottages from about 1916. The ranch is significant for the Del Valle family's agricultural and winemaking history and for its association with Helen Hunt Jackson's novel Ramona. After the book appeared in 1884 and the Southern Pacific arrived in 1887, visitors came to see the supposed home of the heroine, and the ranch was photographed, painted, and filmed in 1910. Its plan, setting, and working citrus landscape remain largely intact.","period_of_significance":"1853-1941","architect_builder":"Ygnacio del Valle family (adobe); August Rubel (schoolhouse, c. 1930); Southern Pacific Railway (section house, 1887)","architectural_style":"Spanish Colonial; Mission/Spanish Colonial Revival; Bungalow/Craftsman","criteria":[],"status_note":"Still operated as an active citrus ranch; the adobe shows ongoing repair, and a January 1994 earthquake caused damage, including to a water tower that was demolished.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:32.138507-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/96001137_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/96001137/74faf18345-800.webp","url_1600":"https://nationalhistoricalregister.com/media/96001137/74faf18345-1600.webp","licence":"Public domain","author":"Norris M.
