Remarkably, Spokane hosted the World's Fair in 1974, the smallest community to have done so in all the years of World's Fair-ing. 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 "the Environment," and the event, if nothing else, transformed the industrial island into the more pleasant Riverfront Park.
