Sears Tower – Icon of the Birthplace of the Skyscraper

Posted by Jae on January 6, 2009


Sears Tower

Let’s start my first post about a skyscraper with the most prominent building of the city that started it all… the 6th tallest in the world, office-use, 1973 completed, 150 million dollar (equivalent to about 1 billion current US dollars), 108 floor, 442 m Sears Tower in Chicago, USA.  The Sears Tower remains the tallest skyscraper in Chicago, in the Western Hemisphere, and retains the world record as the tallest skyscraper to the top of the antenna at 527 m.  Although it is 26 m shorter than Toronto’s CN Tower (only an observation tower not a fully habitable building thus not a skyscraper), the Sears Tower is the only other freestanding structure in the Western Hemisphere to exceed 500 m in height. The observation deck of the Sears Tower is at a height of 412 m (highest public observation deck in the USA.)  As of January 2009, the Sears Tower is the fourth tallest freestanding structure in the world (by pinnacle height), after the Burj Dubai (under construction), the CN Tower (not a skyscraper) and the Ostankino Tower (not a skyscraper.)  The building’s official address is 233 South Wacker Drive, Chicago, Illinois 60606.

  1. Definitely believe that which you stated. Your favorite reason seemed to be on the web the easiest thing to be aware of.
    I say to you, I certainly get annoyed while people think
    about worries that they plainly don’t know about. You managed to hit the nail upon the top as well as defined out the whole thing without having side effect , people could take a signal. Will probably be back to get more. Thanks
