Capella Tower (also 225 South Sixth) is an office skyscraper in Minneapolis, Minnesota, United States. The building opened in 1992 with the First Bank Place being the headquarters for First Bank System. In 1997, First Bank System acquired US Bancorp and changed the name of the building to US Bancorp Place. The headquarters of US Bancorp moved into the US Bancorp Center in 2000, whereupon the tower changed to 225 South 6th Street. In March 2009, the building took its present name. In March 2008, Capella Education Co., longtime occupant of the building and owner of the for-profit online Capella University, signed a lease that changed the name of the tower to Capella Tower. The new lease expands Capella's square footage in the building from 203,000 sq ft (18,900 m2) to about 400,000 sq ft (37,000 m2), making it the largest tenant in the building. The ranking of the building as the tallest in Minneapolis is in dispute. The IDS Center is usually said to be taller by one foot, even by the owners of Capella Tower. It was initially said to be built one foot shorter out of respect for the IDS Center; however, in 2005, it was revealed that contractors had surreptitiously added 14 inches (36 centimeters) of height to Capella, therefore making it taller than the main roof of IDS Center.
