Maritime National Historical Park (Aquatic Park) - San Francisco CA The San Francisco Maritime National Historical Park was originally the San Francisco Aquatic Park, created by the Works Progress Administration (WPA) in 1936-1939.
The 32 acre park included a lagoon and a bathhouse. The lagoon was ringed by breakwaters, with three small towers, a promenade and grandstand. The bathhouse was built in the distinctive Streamline Moderne style of the late 1930s and originally housed a restaurant above and showers and dressing rooms in the basement. The Aquatic Park was an extremely popular swimming spot for San Franciscans when it was built.
