Riverfront Park is a public park in downtown Spokane, Washington. The 100 acre park is located along the Spokane River containing the upper Spokane Falls and just upstream from the lower falls. It was created for Expo '74, a World's Fair event. The defining feature of the park is the Pavilion, which is marked by a 145-foot-tall metal frame and wire shell that formed the US Pavilion tent during Expo '74.
