It also holds federally funded 1930s art by Hilaire Hiler, Sargent Johnson and Beniamino Bufano. It has regional military significance as headquarters of Pacific coast anti-aircraft defense in World War II.","narrative":"Aquatic Park is a waterfront recreation complex in San Francisco, built on the site of Black Point Cove, which was partly filled by industry and earthquake debris in the 19th and early 20th centuries. Work funded by the Works Progress Administration produced a new beach, a four-story oval bathhouse designed by William Mooser Sr. and Jr., stadia, a curved municipal pier, a concessions stand, restrooms, a granite-block seawall and two speaker towers. Completed in 1939, the group follows the Streamlined Moderne style, with porthole windows, ship-like railings and rounded walls recalling an ocean liner. Inside the bathhouse are murals, mosaics and sculpture by Hilaire Hiler, Sargent Johnson, Beniamino Bufano and others. The park was listed for its architectural and landscape design, its integrity, and its 1930s federal art. It also served as headquarters for anti-aircraft defense of the Pacific coast states during World War II. The bathhouse now houses a maritime museum.","period_of_significance":"1920-1945","architect_builder":"William Mooser, Sr. and Jr.","architectural_style":"Streamlined Moderne","criteria":[],"status_note":"Largely unaltered since 1939; the bathhouse is now the Maritime Museum building and is in good structural condition, with some moisture damage to concrete walls.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:32.14453-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/84001183_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/84001183/25f60e6cab-800.webp","url_1600":"https://nationalhistoricalregister.com/media/84001183/25f60e6cab-1600.webp","licence":"CC BY-SA 3.0","author":"Almonroth","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Aquatic_Park_Historic_District-27.jpg\" rel=\"noopener\">Almonroth</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:Aquatic_Park_Historic_District-27.jpg"},"district":{"nrhp_refnum":"06000372","name":"Port of San Francisco Embarcadero Historic District","url":"https://nationalhistoricalregister.com/districts/california/port-of-san-francisco-embarcadero-historic-district-06000372/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123858050","wikipedia":"https://en.wikipedia.org/wiki/Aquatic_Park_Historic_District","wikidata":"https://www.wikidata.org/wiki/Q2475631"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/san-francisco/aquatic-park-historic-district-84001183/"}
