Its exterior shows Howard's reinterpretation of the Classic tradition in a regional context, and its interior reflects 19th-century engineering aesthetics. It housed the State's first School of Mining and is tied to George and Phoebe Apperson Hearst.","narrative":"Built between 1902 and 1907 on the University of California's Berkeley campus, this mining building was designed by architect John Galen Howard. It sits north of the Mining Circle and anchored the campus's principal east-west axis. The E-shaped plan has a long south-facing block with three arched, two-story entrances, a red tile roof, and carved brackets and corbels. Inside, a three-story vestibule and museum has skylit domes, exposed steel and Gustavino tile, in an industrial style that echoes a Paris library. Phoebe Hearst commissioned it as a memorial to her husband, Senator George Hearst, and Dean Samuel Christy wanted a workshop for students. Howard and Christy toured American and European mining schools to shape the design. The building housed the State's first School of Mining. It is listed for its architecture, education, engineering and mining associations, and its design served as a prototype for later campus structures. Light courts were enclosed in 1948, and offices have been altered.","period_of_significance":"1900-present","architect_builder":"John Galen Howard","architectural_style":"Beaux-Arts eclectic Classic mode with Mediterranean or California Mission flavor","criteria":[],"status_note":"Condition listed as good and altered, on its original site; light courts were covered in 1948 and interior work spaces were altered, but the form says architectural integrity is not impaired.","vacant_flag":null,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.908106-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/82004646.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/82004646/3018d4ebcd-800.webp","url_1600":"https://nationalhistoricalregister.com/media/82004646/3018d4ebcd-1600.webp","licence":"CC BY-SA 4.0","author":null,"credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Hearst_Mining_Building.jpg\" rel=\"noopener\">Unknown author</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Hearst_Mining_Building.jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123857330","wikipedia":"https://en.wikipedia.org/wiki/Hearst_Memorial_Mining_Building","wikidata":"https://www.wikidata.org/wiki/Q5691716"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/alameda-county/hearst-memorial-mining-building-82004646/"}
