This artificial island was constructed of bay sand in 1936-37 and was the site of Golden Gate International Exposition, Feb. 18, 1939 - Sept. 29, 1940. Tall towers, gigantic goddesses and dazzling lighting effects turned the island into a "Magic City." The exposition celebrated the ascendancy of California and San Francisco as economic, political and cultural forces in the increasingly important Pacific region. Treasure Island has been a U.S. Naval Station since 1941.
