Mare Island Naval Shipyard

Mare Island Naval Shipyard, located in Vallejo, California, was a major U.S. Navy shipbuilding and repair facility established in 1854. It served as a key site for constructing, maintaining, and repairing naval vessels for over a century. The shipyard featured extensive docks, workshops, and support infrastructure. Its strategic position on San Francisco Bay allowed for efficient deployment of naval ships. The yard closed as a military facility in 1996, and today, it has been redeveloped into a mixed-use area with residential, commercial, and recreational spaces, while preserving some historic structures as reminders of its maritime history.
