IDS Tower (tallest building in Minnesota)

The IDS Center (or IDS Tower) is the tallest building in Minneapolis and the state of Minnesota at 792 feet (241.4 m). Opened in 1974 as the IDS Centre, it stood 775 feet 6 inches (236.4 m), though a 16-foot (4.9 m) garage for window washing equipment was added at a later date. In 1992, the 776-foot (236.5 m) tall First Bank Place, now known as 225 South Sixth, was completed nearby. However, it was advertised at the time as 774 feet (235.9 m) tall, one foot (0.3 m) shorter than the IDS "out of respect". A dispute eventually erupted in 2004–2005 and the rooftop garage is now included in the building's height, restoring it to first-place status in the city. Overall, the structure rises to 910 feet (277.4 m) when including communications spires on the roof, indisputably the highest points in the city. The IDS was constructed as the headquarters of Investors Diversified Services, Inc.—now Ameriprise Financial. It also housed the headquarters for the Target stores division of Dayton Hudson Corporation (now Target Corporation) from 1972 until it moved to its own new headquarters building in 2002.
