Willis Tower. The Willis Tower, built as and still commonly referred to as Sears Tower, is a 108-story, 1,450-foot (442.1 m) skyscraper in Chicago, Illinois, United States.
The Willis Tower gets more than $25 million annually, and Riggs said naming rights could boost that when they expire. The agreement was between Blackstone Real Estate Partners VII and 233 South Wacker Drive LLC. The owners paid $841 million for the property in 2004. The building was the worldâs tallest from when it opened in 1973 until 1998. On a square-foot basis, the price for the Willis Tower was about $340, a fraction of what trophy towers fetch in major cities, MarketWatch said.
