Hate waiting for elevators? You might want to consider finding yourself a job inside the former headquarters of Sears, Roebuck, and Company; it has 103 of them so, chances are, there will always be one waiting for you. The skyscraper, formerly known as the Sears Tower (a name which is still commonly used), is actually nine square buildings bundled together; an engineering strategy to help the 110 storey structure resist Chicago’s infamously high winds. When it finished construction in 1974, it was the world’s tallest building at 1,451 feet. The 110 storey building lost that title to the Petronas Towers in Kuala Lumpur, Malaysia in 1998. The Skydeck, on the 103rd floor, allows visitors the best view of the city and provides an interactive experience. Those with a strong constitution can even step out into one of several glass boxes that hang over the building’s ledge.
