Visitors can reach the top of the Space Needle via elevators that travel at 10 mph (16 km/h). The trip takes 43 seconds, and some tourists wait in hour-long lines in order to ascend to the top of the tower. On windy days, the elevators are slowed down to a speed of 5 mph. The Space Needle was designated a historic landmark on April 19, 1999 by the City's Landmarks Preservation Board

Edward E. Carlson, chairman of the 1962 World's Fair in Seattle, originally had an idea for erecting a tower with a restaurant at the World's Fair. Carlson was then president of a hotel company and not previously known for art or design, but he was inspired by a recent visit to the Stuttgart Tower of Germany.

John Graham, an architect who had won praise for designing Northgate Mall in Seattle soon became involved. Graham's first move was to make the restaurant featured in the plans revolve, in the same manner as a tower he had previously designed for the Ala Moana Shopping Center in Honolulu
