It is a one- to two-story rectangle around a central atrium court, now used as an art center and museum.","why_significant":"It was the first permanent home of both the Riverside YWCA and, later, the Riverside Art Center and Museum. It was designed by Julia Morgan, a major California architect, and is ranked among her more important buildings in Southern California. The form calls it an extremely important part of Riverside's architectural heritage.","narrative":"Built in 1929 at 3425 7th Street in Riverside, this reinforced-concrete building was designed by architect Julia Morgan for the local YWCA. Its Mediterranean style shows Italian and Spanish influences, with red tile roofs, round-headed windows, loggias with floral-capital columns, and wrought-iron details. Rooms are arranged around a central atrium that was designed as a dining area, and the building once held a gymnasium, a swimming pool and a rooftop tennis court. The lot was donated by Frank Miller. The YWCA, established in Riverside in 1906, used the building until 1966, when it was sold to the Riverside Art Center and Museum, which made it that group's first permanent home. The conversion brought mostly reversible changes, such as filled-in windows and a gymnasium turned into a gallery. Its significance rests on its architecture, as one of Morgan's more important Southern California works, and on its role in the social history of the YWCA in Riverside.","period_of_significance":"1929-1966","architect_builder":"Julia Morgan, architect; Nethery Co., builders","architectural_style":"Mediterranean with a dominant Italian influence and Spanish overtones","criteria":[],"status_note":"Occupied and in good condition; in use as an art center and museum since 1966, with some alterations but described as fundamentally intact.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.876528-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/82002227.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82002227/46cfd69f8e-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82002227/46cfd69f8e-1600.webp","licence":"Public domain","author":null,"credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:RiversideArtMuseum20090821g.JPG\" rel=\"noopener\">Unknown author</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:RiversideArtMuseum20090821g.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123860503","wikipedia":"https://en.wikipedia.org/wiki/Riverside_Art_Museum","wikidata":"https://www.wikidata.org/wiki/Q7338423"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/riverside-county/old-ywca-building-82002227/"}
