The Willis Tower (formerly named, and still commonly referred to as, the Sears Tower) is a 108-story, 1,451-foot (442 m) skyscraper in Chicago, Illinois, says Wikipedia.[4]
At the time of its completion in 1973, it was the tallest building in the world, surpassing the World Trade Center towers in New York, and it held this rank for nearly 25 years. The Willis Tower is the tallest building in the United States and the seventh-tallest freestanding structure in the world.
Located on the 103rd floor of the tower is one of the most famous tourist attractions in Chicago, the Skydeck. Tourists can experience how the building sways on a windy day. They can see far over the plains of Illinois and across Lake Michigan to Indiana, Michigan and Wisconsin on a clear day.
Elevators take tourists to the top in about 60 seconds. The Skydeck competes with the John Hancock Center's observation floor a mile and a half away, which is 323 feet (98 m) lower.
Some 1.3 million tourists visit the Skydeck annually.
