Which building was formerly called the Sears Tower?

• Willis Tower:Formerly known as the Sears Tower, Chicago’s tallest skyscraper was built in 1970 by Sears, Roebuck & Co., then the largest retailer in the world. At its completion in 1974, it surpassed the World Trade Center in New York City to become the tallest building in the world, a title that it held for nearly 25 years. The black-banded building dominates the Windy City’s skyline and, at 108 stories, it is currently the third-tallest building in the United States – and the 23rd-tallest in the world. More than one million people visit its observation deck each year, making it one of Chicago's most popular tourist destinations. The structure was renamed in 2009 by the Willis Group as a term of its lease on a portion of the tower's space.
