Or should I say expositions?
There were
way too many to recall. The 1st one, Panama–Pacific International Exposition, held from Feb 20 to Dec 4, 1915 was to celebrate the rebuilding of the new SF after the '06 quake but its foremost purpose was to celebrate the completion of the Panama Canal. The fair was constructed on 635 acre in SF, along the northern shore (Marina).
Among the exhibits were
C.P. Huntington, the 1st steam locomotive purchased by Southern Pacific Railroad, which is now on static display at the CA State Railroad Museum in Sacramento, our state capitol. A telephone line was also established so people across the continent could hear the Pacific Ocean. The Liberty Bell travelled by train to and from PA in nationwide tour to attend the exposition. After that, the Liberty Bell returned to PA, never to be moved again.
The centerpiece of the Expo was
Tower of Jewels, which rose to 435 feet and was covered with over 100,000 cut glass
Novagems. The 3/4 to 2 inch colored "gems" sparkled in sunlight throughout the day and were illuminated by over 50 powerful electrical searchlights at night.
In front of the Tower, the Fountain of Energy flowed at the center of the South Gardens, flanked by the Palace of Horticulture on the west and the Festival Hall to the east. The arch of the Tower served as the gateway to the Court of the Universe, leading to the Court of the Four Seasons to the west and the Court of Abundance to the east. These courts formed the primary exhibit area for the fair, which included the Food Products Palace, the Education and Social Economy Palace, the Agriculture Palace, the Liberal Arts Palace, the Transportation Palace, the Manufacturers Palace, the Mines and Metallurgy Palace, and the Varied Industries Palace. The Machinery Palace, the largest hall, dominated the east end of the central court.
At the west end of central court group was the
Palace of Fine Arts. Further west toward the bay down The Avenue of the Nations were national and states' buildings, displaying customs and products unique to the area represented.
At the opposite end of the Fair, near
Fort Mason (then an active Naval station, now a center for non-profit organizations) was
The Zone, an avenue of popular amusements and concessions stands.
Most of the buildings were demolished except for the Palace of Fine Arts, which still stands today although reconstructed in the '60s.
The Golden Gate Int'l Exposition of 1939 and 1940, held at Treasure Island, was to celebrate the City's two newly-built bridges-SF-Oakland Bay Bridge was dedicated in 1936, and the Golden Gate was dedicated in 1937. The Exposition happened from Feb 18, 1939 to Oct 29, 1939 and it opened again in May 25, 1940 to Sept 29, 1940. I guess they didn't have enough of us, so they need to have us twice in a row!
