The tallest skyscraper in the U.
S., it has stood as the tallest for 35 years. It's located in
Chicago, Illinois.
The tower has 108 floors, although occasionally the main roof and mechanical penthouse are counted as floors 109 and 110.
Bruce
Graham was the chief architect for this building.
The Sears Tower has two large antennas which increase its height dramatically.
On a clear
day, you're able to see across Lake Michigan to Indiana, Michigan and Wisconsin from the observation
deck on the 103rd floor.
The building leans slightly, about 4 inches due to its slightly asymmetrical design, this can sometimes be felt by tower inhabitants.
