The Space Needle is a tower in Seattle, Washington and is a major
landmark of the Pacific Northwest region of the United States and a
symbol of Seattle. Located at the Seattle Center, it was built for the
1962 World's Fair, during which time nearly 20,000 people a day used the
elevators, with over 2.3 million visitors in all for the World Fair.
The Space Needle is 605 feet (184 m) high at its highest point and 138
feet (42 m) wide at its widest point and weighs 9,550 tons. When it was
completed it was the tallest structure west of the Mississippi River.
It is built to withstandwinds of up to 200 miles per hour (89 m/s) and
earthquakes of up to 9.1 magnitude, which would protect the structure
against an earthquake as powerful as the 1700 Cascadia earthquake. The
tower also has 25 lightning rods on its roof to prevent lightning
