Crystal Court

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

The complex consists of five parts: the 57-story IDS Tower itself at 8th Street & Nicollet Mall, an 8-story annex building along Marquette Avenue, the 19-story Marquette Hotel at 7th Street & Marquette Avenue, and a 2-story retail building that was originally dominated by Woolworth's.
