The Panama-Pacific International Exposition (PPIE) was a worlds fair held in held in San Francisco between February 20 and December 4 in 1915. Its ostensible purpose was to celebrate the completion of the Panama Canal, but it was widely seen in the city as an opportunity to showcase its recovery from the 1906 earthquake. The fair was constructed on a 635 acre (2.6 km²) site in San Francisco, along the northern shore now known as the Marina.
