On November 2, 1915, San Francisco threw open its gates to a glorious world's fair.

A reborn fog city hit the spotlight when the Panama-Pacific Exposition celebrated San Francisco Day. At around 348,472 attendees, the occasion brought in 70% of the city's population. As one of the largest events in SF history, the exposition was organized to commemorate the construction of the Panama Canal, as well as the city bouncing back after the 1906 earthquake. Attend this fantastical affair through vintage photos, drawings, and memorabilia.

This map of the Panama-Pacific International Exposition shows all the buildings that were created for this grand event. Hydraulic pumps were used to fill the swampland in what is now The Marina. The only remaining structure from the PPIE that still stands today is the Palace of Fine Arts, which was reconstructed in the 1960s.
