The Space Needle is a tall, flying-saucer-shaped tower in the middle of Seattle. A super-fast elevator carries you up to a viewing deck where you can see the whole city, the water, and the mountains.
It was built for the 1962 World's Fair and quickly became the symbol of Seattle. Kids love its glass floor that slowly spins, letting you look straight down at the ground far below.
From 520 feet up you can spot the harbor, sailboats, and even Mount Rainier on a clear day. On both sides big windows tilt outward so you feel like you are floating.
The lower deck has the world's first rotating glass floor, called The Loupe. You can sit on clear benches and watch the city turn slowly beneath your feet.
The tower was designed for a fair all about the future and space travel. It was built in just about a year and has welcomed millions of visitors ever since.
