For many of the millions of visitors from around the world who attended, the fair represented their first opportunity to see such technological marvels as the airplane.
The fair was constructed on a 635-acre site in San Francisco, along the northern shore now known as the Marina.
Among the exhibits at the Exposition was C. P. Huntington, the first steam locomotive purchased by Southern Pacific Railroad. A telephone line was also established to New York so people across the continent could hear the Pacific Ocean.
The Liberty Bell traveled by train on a nationwide tour to and from Pennsylvania to attend the exposition. After that trip, the Liberty Bell returned to Pennsylvania and would not be moved again.
