Space Needle
This landmark is the Space Needle in Washington state. Edward E. Carlson was the chief organizer of the World’s Fair. He came up with the tower idea and drew a flying saucer concept on a napkin. The Space Needle only took 400 days to build and opened to the public on April 21, 1962, for the Century 21 Exposition. The tower is 605 feet high (184 meters), and in 1999, this city’s preservation board designated it a historic landmark.
