The Flag of the City and County of San Francisco contains a rising phoenix in the center, often assumed to refer to the city's recovery from the 1906 earthquake and subsequent fires. However, the phoenix had been a civic symbol of San Francisco at least since 1852, when it featured on the first official seal of the city. The Board of Supervisors of the City and County of San Francisco codified the design of the current flag on December 16, 1940.
