The Golden Gate International Exposition (GGIE) was a massive undertaking. The city of San Francisco had long looked for a site for a new airport to service the Pacific market, and the fair provided the impetus to build Treasure Island, a man-made island that would eventually service the massive seaplanes in use at the time. The GGIE also helped cement the Bay Area as a tourism and business center, competing directly with the 1939-1940 New York World's Fair. While New York centered more on the industrial side, the GGIE showcased the many natural wonders of the West, with expansive gardens and complementing architecture. The GGIE was a success on all counts, enticing millions of visitors to travel to the region. When the fair was over, Treasure Island became an important naval base during World War II.
