The History of Treasure Island
Treasure Island is a man-made island connected via causeway to Yerba Buena Island, in the middle of San Francisco Bay. Treasure Island was constructed in the 1930s to celebrate the opening of the Bay Bridge and the Golden Gate Bridge and was used to host the 1939 International Golden Gate Exhibition, a World’s Fair event.
As World War II began, the U.S. Navy established Naval Station Treasure Island as a reception center for sailors headed to the Pacific. It later served as a training and auxiliary aircraft facility.
