100 Washington Square is a 332-ft (101 m) tall skyscraper in Minneapolis. It was completed in 1981 and has 22 floors. It is the 26th tallest building in the city. The building was designed by architect Minoru Yamasaki, the same responsible for the design of the World Trade Center in NYC. As with the Trade Center, the exterior of the building is composed of closely spaced load-bearing steel that distributes weight to the core and removes the need for internal support columns.
