That title, held by the Empire State Building in New York for more than 40 years from 1931 on, was taken over by the twin towers of the World Trade Center of New York in 1972. But that record was held only two years.
In 1974, the Sears Tower in Chicago, Illinois, claimed the title as the world’s tallest building. It stands 1,454 feet (443 meters) from the sidewalk to the roof, as compared to the World Trade Center’s 1,350 feet (411 meters) and the Empire State Building’s 1,250 feet (381 meters).
The Sears Tower has 110 stories and cost $200 million to build. It is actually a cluster of nine dark glass and steel boxes bundled together and cut off at various heights. As architects seem to be playing “Can You Top This?” with skyscrapers, it might not be surprising to see buildings reach a height of 2,000 feet by the year 2000.
The Sears Tower also has the world’s fastest passenger elevator, traveling at a speed of over 20 miles per hour. The express elevator takes passengers from the ground floor to the 103rd floor in 45 seconds!
