The 110-story Sears Tower, tallest office building in the Western Hemisphere, will be renamed the Willis Tower, global insurance broker Willis Group Holdings said on Thursday.

Willis said it was leasing multiple floors in the 1,451-foot (442-meter) structure in downtown Chicago to consolidate offices. As part of the deal, it will become the Willis Tower this summer when the move takes place, the company said.

Sears, once the largest U.S. retailer, occupied what was then the world's tallest building as its headquarters after the skyscraper was completed in 1973. But it moved out in the early 1990s.

What a shame. And what an ugly name! It's like renaming the Statue of Liberty something like "The Insurance Statue."
