The IDS Center is an office skyscraper located at 80 South 8th Street in Minneapolis, Minnesota. Completed in 1973, it is the tallest building in Minneapolis, and the tallest building in the state at a height of 792 feet (241 m). It originally stood 775 feet 6 inches (236.37 m), though a 16-foot (4.9 m) garage for window washing equipment was added between 1978 and 1979. The structure rises to 910 feet (10,900 in) 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 of Dayton Hudson Corporation (now Target Corporation) from 1972 until 2001.
