The Space Needle was designed for the 1962 Seattle World’s Fair Exhibition. Set on the only section of the fair grounds that was not owned by the city, the site did not have the height restrictions of other exhibits/pavillions at the fair. The lot, 37-by-37 m, was purchased by private investors for $75,000 and is still privately owned. Standing 605 feet (184 meters) in the air on massive steel beams that form its slender legs, the Space Needle has since become the internationally recognized symbol of Seattle. The Space Needle was completed in December 1961, and officially opened four months later on the first day of the World’s Fair, April 21, 1962. Although there is much contention surrounding who came up with the final design of the Space Needle, John Graham is widely acknowledged as its architect. Edward Carlson and Victor Steinbrueck are also credited with having come up with elements of the design.
