The flag of the city of San Diego, California, is an equal vertical tricolor of red, white, and golden yellow, with a stylized version of the San Diego city seal in the center of the flag, entirely inside the white stripe. Semicircling the lower section of the city seal, in black, is the word "1542".
The city seal represents the city of San Diego and its citizens. 1542 is the year that Juan Rodriguez Cabrillo claimed the current San Diego area for Spain, whose colors, red and gold, are represented on the San Diego city flag.
