Mountain Street, Pasadena, California, completed in 1887 and designed by architect Harry Ridgway for Romayne Williams.","why_significant":"The nomination argues the house is an exceptional local example of high-style Queen Anne architecture and a master work of Harry Ridgway, retaining a high level of authenticity inside and out. It is also tied to Romayne Williams, an early and influential Pasadena citizen and merchant.","narrative":"Completed in 1887 at the corner of North Hill Avenue and East Mountain Street in Pasadena, Hillmont is a Queen Anne style country house built for early settler and merchant Romayne Williams. Architect Harry Ridgway, described as the most prolific architect in Pasadena in the late nineteenth century, designed it. The foundation and first floor are green Tehachapi sandstone with extensive tooling, while the upper story is clad in fish-scale shingles beneath steep hipped and gabled roofs. Verandas, carved ornament, and 32 stained glass windows distinguish the house, and each interior room is finished in a different wood. The nomination credits detailing influenced by English designers and Scandinavian folk ornament. Williams arrived in Pasadena in 1877, ran a general store that served as a civic hub, and took part in utility, railway and banking ventures. He lost his money five years after the house was finished and sold it. The house remains in its original location on a large lot and keeps a high degree of authenticity.","period_of_significance":"1887","architect_builder":"Ridgway, Harry (architect)","architectural_style":"Late Victorian/Queen Anne","criteria":["B","C"],"status_note":"Still used as a single dwelling; retains integrity of location, design, setting, workmanship, materials, feeling and association, though the original stables are lost and a 1927 garage is non-contributing.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:54:29.776891-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/11000493.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/11000493/327b0fc497-800.webp","url_1600":"https://nationalhistoricalregister.com/media/11000493/327b0fc497-1600.webp","licence":"CC BY-SA 3.0","author":"TheCatalyst31","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hillmont,_Pasadena,_CA,_from_SE.JPG\" rel=\"noopener\">TheCatalyst31</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:Hillmont,_Pasadena,_CA,_from_SE.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123857484","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q133289920"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/los-angeles-county/hillmont-11000493/"}
