The flag of the City and County of San Francisco, which depicts a rising phoenix, is often assumed to be symbol of the city’s recovery from the 1906 earthquake and subsequent fires. However, the flag traces its origins to 1900. The Board of Supervisors of the City and County of San Francisco codified the design of the current flag on December 16, 1940. Full HD.
