The 1915 World's Fair
The 1915 World's Fair took place in San Francisco at what is today the Presidio and the Marina District. Officially called the Panama-Pacific International Exposition, the fair celebrated the successful 1914 completion of the Panama Canal, which connected the Atlantic and Pacific Oceans. Locally, the 1915 World's Fair was San Francisco's opportunity to prove that the city, by then fully recovered from its devastating 1906 earthquake, was open for business.
