Century 21 Exposition

About

The Century 21 Exposition (also known as the Seattle World's Fair) was a world's fair held April 21, 1962, to October 21, 1962, in Seattle, Washington, United States. Nearly 10 million people attended the fair during its six-month run.

As planned, the exposition left behind a fairground and numerous public buildings and public works; some credit it with revitalizing Seattle's economic and cultural life (see History of Seattle (1940–present)). The fair saw the construction of the Space Needle and Alweg monorail, as well as several sports venues (Washington State Coliseum, now Climate Pledge Arena) and performing arts buildings (the Playhouse, now the Cornish Playhouse), most of which have since been replaced or heavily remodeled. Unlike some other world's fairs of its era, Century 21 made a profit.
