The house was completed in 1877 for rancher William R. Roberts.","why_significant":"The nomination argues the house is an unusually fine and rare example of Victorian Gothic design in Sonoma County, notable for its thirteen gabled window hoods and distinctive keyhole-shaped windows. It is also the historic residence and remaining core of Roberts Ranch, tied to the settlement and agricultural development of the area. It has been recognized locally, including as a Sonoma County Landmark.","narrative":"Built in 1877 for rancher William R. Roberts, The Gables is a two-story Victorian Gothic house on Petaluma Hill Road, three miles south of Santa Rosa. Its redwood frame carries thirteen steeply pitched gabled hoods over the upper windows, and nearly every window and door repeats a flattened, keyhole-like Gothic arch. Inside are a carved winding staircase, twelve-foot ceilings, plaster medallions and three marble fireplaces. The remaining 3.19 acres of what was once a ranch of nearly 1,200 acres also hold an 1880 barn, chicken coops, an 1877 outhouse, a moved cottage and later dairy buildings. Roberts, a forty-niner who settled the land in 1852, built a dairy, grain and sheep operation before his death in 1881. The house is considered a rare, little-altered example of its style, with an unknown architect, and it is a designated Sonoma County Landmark. It remains a private residence in excellent condition.","period_of_significance":"1800-1899","architect_builder":"Unknown","architectural_style":"Victorian Gothic","criteria":[],"status_note":"Occupied as a private residence; described as in excellent condition with only minor alterations.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:28.32758-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/84001206.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/84001206/5eadcf922f-800.webp","url_1600":"https://nationalhistoricalregister.com/media/84001206/5eadcf922f-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:The_Gables,_4257_Petaluma_Hill_Rd.,_Santa_Rosa,_CA_6-12-2010_8-38-14_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:The_Gables,_4257_Petaluma_Hill_Rd.,_Santa_Rosa,_CA_6-12-2010_8-38-14_PM.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123862064","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q56567827"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/sonoma-county/gables-the-84001206/"}
