Wanderlust World Wanderlust World Angel Island, the largest natural island in San Francisco Bay, has worn at least four distinct names reflecting its layered history under Spanish, Mexican, and American sovereignty.
Spanish naval officer Juan Manuel de Ayala charted San Francisco Bay in 1775, naming the island "Island of the Angels" during the Feast of Our Lady of the Angels. This represents the first European place name for the island.
Early Spanish and Mexican settlers referred to the island as Alameda ("grove of poplars" or "tree-lined avenue"), likely describing its once-extensive oak and bay laurel woodlands. The name later transferred to the adjacent mainland city.
American Colonel Jonathan Stevenson, commanding the 1st Regiment of New York Volunteers during the Mexican-American War, dubbed it "Wood Island" for its timber resources—critical for construction and fuel in the newly American territory.
During the Civil War, the U.S. Army briefly designated the island as "East Fort Alcatraz" while constructing defensive fortifications (Camp Reynolds) to protect San Francisco Bay from potential Confederate raiders. The name reflected its strategic relationship to Alcatraz Island's fortifications.
Each name marks a transition: Spanish exploration → Mexican rancho era → American military occupation → Civil War defense. The island later served as an immigration station (1910-1940, "Ellis Island of the West"), Nike missile site (1950s-60s), and today as a state park preserving this multilayered history.
Angel Island's name changes chronicle the geopolitical struggle for control of San Francisco Bay—one of the world's great natural harbors.
