In celebration of Expo ’74 50th Anniversary, the Spokane Pavilion and Clock Tower will light up the night sky at Riverfront Park. These landmarks hold rich ties to the fair’s history. The Pavilion originally served as the U.S. Federal Pavilion, and the Clock Tower is the last remaining structure of the Great Northern Railroad depot that was demolished to clear the site for Expo ’74. Stop by Friday – Sunday to check out the dazzling light shows!
