“Seattle was a gas in the 1960s. The Century 21 Exposition, also known as the Seattle World’s Fair, was held in 1962 and drew almost 10 million visitors from around the globe. The space exploration-theme of the fair inspired major construction projects including the Space Needle and Alweg monorail, as well as several sports venues (Washington State Coliseum, now KeyArena), performing arts buildings (the Playhouse, now the Cornish Playhouse), and the Pacific Science Center.”
