The first official seal of Solano County was adopted by the Board of Supervisors on April 20, 1965.  The seal is rich in symbolism that reflects the history and values of Solano County. 

The pillars from the Old State Capital building in Benicia are incorporated into the border of the design.  Dominating the outline of the county is the figure of Chief Solano, for whom the county is named.  Inside the county outline you can see the vast agriculture area surrounded by blue skies, mountains and waterways.

The U.S. Armed Forces are part of Solano County – both past and present.  The large aircraft reflects the mission of Travis Air Force Base and the ships reflect the former Mare Island Naval Shipyard.

The golden rays indicate the benign climate Solano County residents enjoy, and the recreational boat showcases the outdoor amenities that abound in the county.
