The Sears Tower looms over downtown Chicago, an unmistakable symbol of the city's pride in its heritage as the birthplace of a uniquely American concept, the modern skyscraper. Built in 1974 to a height of 1,468 feet, the Sears Tower succeeded the Empire State Building as the world's tallest building, and held that title until 1996. The building was designed by the distinguished and world famous firm of architects, Skidmore, Owings and Merrill to serve as the corporate headquarters for Sears Roebuck and Company. Its architectural style, while incorporating significant engineering advances, relates back to the impersonal glass boxes of the 1950s and 1960s rather than looking forward to the more idiosyncratic towers of the 1980s and 1990s. Though large and impressive, the building never quite captured the hearts of Chicago's citizens in the way that the city's John Hancock Center did. Nevertheless, the Sears Tower epitomizes the bustling prairie metropolis that Carl Sandburg called the "City of Big Shoulders."

SEARS TOWER was built in downtown Chicago as the headquarters of Sears, Roebuck & Co. It opened in 1974 as the world's tallest building, 1,474 feet, with 110 stories and 4.5 million square feet of office space. The building was designed by architects Skidmore, Owings & Merrill, and constructed in only thirty months. Engineer Fazlur Khan structured the building as nine square tubes of varying heights, bundled together to resist high winds. Most Sears operations were moved to a suburban location
in 1995. In 1998, Sears Tower was officially surpassed as the world's tallest building by the Petronas Towers in Kuala Lumpur, Malaysia.
