Mare Island keeps Vallejo's naval story in everyday view
Mare Island was the first U.S. naval station on the West Coast, and today Vallejo ties that history to reuse, businesses, trails, housing, schools, and open space.
Mare Island is the part of Vallejo history that still shapes the map. Naval work began there in 1854. It became the first U.S. naval station on the West Coast.
That first matters because California had only recently become a state. A naval station on this side of the country tied Vallejo to ships, industry, military work, the Carquinez Strait, and the wider Pacific.
The naval yard closed in 1996, but the island did not disappear from city life. Vallejo now has businesses, Touro University, trails, history sites, housing, and a nature preserve as part of the Mare Island mix.
That reuse layer makes the place more interesting. Mare Island is not frozen in one era. It is naval history, waterfront land, new uses, open space, and everyday Vallejo all sharing the same island.
