Sears Tower Renamed

The tallest tower in the United States was renamed early this month and given the name of its new tenant. The Sears Tower in Chicago is now the Willis Tower after London-based insurance brokers Willis Group Holdings.

The 110-storey skyscraper was opened in 1973. Sears Roebuck moved out in 1992.

Willis Group are leasing 140,000 square feet of space in the tower.
