Skyscrapers: Columbia Center

With an imposing presence in the city, the Columbia Center rises 285 metres (937ft) above the streets of downtown Seattle, in Washington State. The Columbia Center encompasses 76 floors, the 73rd of which contains an observation deck, and over 140,000 square metres of floor space.

When opened in 1984, the building was originally called the Columbia Center. It then changed to Columbia Seafirst Center, then Bank of America Tower in 1999. It changed again in 2005 back to its original name. Until the completion of LA's US Bank Tower (or Library Tower) in 1993, it was the tallest American building west of the Mississippi.
