The five level top house dome was completed with special attention paid to the revolving restaurant level and Observation Deck. The top house was balanced so perfectly that the restaurant rotated with just a one horsepower electric motor. In keeping with the 21st Century theme, the final coats of paint were dubbed Astronaut White for the legs, Orbital Olive for the core, Re-entry Red for the halo and Galaxy Gold for the sunburst and pagoda roof. The 605-foot tall Space Needle was completed in December 1961 and officially opened a mere four months later on the first day of the World’s Fair, April 21, 1962.
