Seattle Space Needle

The Seattle Space Needle is one of many icons of Seattle, WA.
It all started in 1959. Edward E. Carlson penciled the shape that would become the internationally known symbol for Seattle, the Space Needle for the futuristic World's Fair in Seattle.
The first obstacle was the structure's design. Carlson's initial sketch went through many changes. One drawing looked like a balloon-shaped top house on a central column anchored by cables. Architect John Graham, designed the world's first shopping mall (Seattle's Northgate), helped Carlson by turning the balloon design into a flying saucer.
The next challenge was location and financing. Since the Space Needle was to be privately financed, it had to be on land which could be used by the public. Early investigations said that the land didn't exist. Just before the search was abandoned, a 120-foot-by-120-foot piece of land was found and sold to investors for $75,000 in 1961, just 13 months before the World's Fair opening.
Construction, managed by the Howard S. Wright Construction Company, progressed quickly. An underground foundation was poured into a hole 30 feet deep and 120 feet across. It took 467 cement trucks an entire day to fill the hole, the largest continuous concrete pour ever attempted in the West. Once completed, the foundation weighed as much as the Space Needle itself, establishing the center of gravity just above ground.
The five level top house dome was completed with special attention paid to the revolving restaurant level and Observation Deck. The top house was balanced so perfectly that the restaurant rotated with just a one horsepower electric motor. In keeping with the Century 21 theme, the final coats of paint were dubbed Astronaut White for the legs, Orbital Olive for the core, Re-entry Red for the halo and Galaxy Gold for the sunburst and pagoda roof. The 605-foot tall Space Needle was completed in December 1961 and officially opened a mere four months later on the first day of the World's Fair, April 21, 1962.
The Space Needle's elevators were the last pieces to arrive before the opening, the last one just one day before the fair opened. New, computerized elevators were installed in 1993. The elevators travel 10 mph, 14 feet per second, 800 feet per minute, or as fast as a raindrop falls to earth. In fact, a snowflake falls at 3 mph, so in an elevator during a snowstorm it appears to be snowing up.
Storms occasionally force closure of the Space Needle, as they did for the Columbus Day storm of 1962 and the "Inauguration Day" storm of 1993 when winds reached 90 miles per hour. The Needle is built to withstand a wind velocity of 200 miles per hour. The Space Needle has withstood several tremors, too, including a 2001 earthquake measuring 6.8 on the Richter scale. The tallest building west of the Mississippi River when it was built, the Space Needle has double the 1962 building code requirements, enabling the structure to withstand even greater jolts.
The Space Needle was built for just $4.5 million, and has had its share of milestones, including numerous weddings and a jump by six parachutists. During the World's Fair, nearly 20,000 people a day traveled to the top. The Space Needle hosted over 2.3 million visitors during the Fair and is still, over 40 years later, Seattle's number one tourist destination.
In 2000, the Space Needle completed a $20 million revitalization. The year-long project included construction of the Pavilion Level, SpaceBase retail store, SkyCity restaurant, O Deck overhaul, exterior lighting additions, Legacy Light installations, exterior painting and more.information & pictures from: spaceneedle.com, google.com
