Photos: Happy birthday! Space Needle celebrates 55 years
SEATTLE - The 1962 World's Fair ended over half a century ago, but the giant needle-shaped tower we built still stands.
Friday marks the Space Needle's 55th anniversary. The 3,700 ton structure attracts millions of visitors each year and cost about 4.5 million dollars to build.
At the time of it's construction, the Space Needle was the tallest building west of the Mississippi River. It was considered very futuristic and was originally going to be called the "Space Cage".
The building is 605 feet tall, 138 feet wide and built to withstand winds of up to 200 miles-per-hour.
On April 21, 1999, it was named an official City of Seattle Landmark by the city's Landmark Preservation Board.
