The former Mare Island Naval Shipyard was the first permanent naval installation on the West Coast when it was founded in 1854.
It built more than 500 ships in its 142-year service to the United States before closing in 1996. Today, much of Mare Island’s historical artifacts are carefully being preserved by the Mare Island Historic Park Foundation.
It’s housed in Building 46, a 50,000-square-foot space built in 1855.
Location: Eighth Street and 1100 Railroad Avenue, Vallejo
