The Space Needle is an observation tower in Seattle, Washington, United States. Considered to be an icon of the city, it has been designated a Seattle landmark. Located at 400 Broad Street in the Lower Queen Anne neighborhood, it was built in the Seattle Center for the 1962 World's Fair, which drew more than 2.3 million visitors.

At 605 ft (184 m) high, the Space Needle was once the tallest building west of the Mississippi River in the United States. The tower is 138 ft (42 m) wide, weighs 9,550 short tons (8,660 metric tons), and is built to withstand winds of up to 200 mph (320 km/h) and earthquakes of up to 9.0 magnitude, as strong as the 1700 Cascadia earthquake.
