Official City of San Diego Seal

The official seal of the City of San Diego consists of a coat of arms within a circle. Above the arms are the names of the City and the state, and below the arms is the City’s official motto. official seal of the City of San Diego

In the 1913, the City Council authorized the City Clerk to invite design submissions for an official seal. The winning design was the work of architect Carleton Monroe Winslow (1876-1946). Winslow would go onto design multiple buildings for the Panama-California Exposition in Balboa Park, and the Bishop's School in La Jolla. The seal was adopted by Resolution 17024 on April 15, 1914.

The seal’s heraldic description is:

Shield: Or (gold/yellow), a fess wavy Azure (blue); in chief a Spanish caravel in full sail Gules (red), pennons and flag Gules; in base an orange tree Proper, fruited and eradicated; between two winged wheels Gules.

Crest: A Carmelite belfry Azure, having hung therein a bell Or.

Supporters: The pillars of Hercules Azure, entwined with ribands Or.

Compartment: Two dolphins Vert (green), with eyes, fins and tail Gules, their tails linked together Or.

Motto: Semper Vigilans

The blue wavy band represents the City's position on the sea. The caravel represents the exploration and settlement by the Spanish. The orange tree represents agriculture, and the winged wheels represent manufacturing and transportation. The belfry suggests early settlement by the mission fathers. The pillars of Hercules are used as supporters to recall the ancient territorial jurisdiction of Spain. Similar pillars are part of Spain’s coat of arms. The two connected dolphins symbolize the Pacific and Atlantic oceans, inseparably united by the Panama Canal. The motto, "Semper Vigilans," is Latin for "Always Vigilant."

There are two discrepancies in the seal's design. First, San Diego was founded by Franciscan priests, not Carmelites. Second, the ship was most likely supposed to represent the ship of Juan Rodriguez Cabrillo, the first European explorer to enter San Diego Bay. However, Cabrillo's flagship San Salvador was a galleon, not a caravel.
