Spokane World's Fair Site, Washington

Spokane hosted the World's Fair in 1974, the smallest community to have done so at the time. The flavor of the era is well preserved in some of the unusual, decaying Expo buildings that remain at the downtown fairgrounds, on Havermale Island, next to the Spokane Falls. The theme of the fair was "Preserve the Environment," and the event, if nothing else, transformed the industrial island into the more pleasant Riverfront Park.The building which housed the United States Pavilion now contains an IMAX theater, while the building which was once served as the Washington State Pavilion, is now part of the Spokane Convention Center.
