Columbia Center

The Columbia Center is a 1985 completed, 76 floor, 285 m skyscraper in Seattle, USA. (The tower was originally named the Columbia Center when it was first built. The name was later changed to Columbia Seafirst Center, for Seafirst Bank, and then to the Bank of America Tower, when Seafirst, which had been owned by Bank of America since 1983, was fully integrated into Bank of America. In November 2005, the building’s name was changed back to the Columbia Center. However, Bank of America still has a branch in the building.) Standing at a height of 285 m, it was the tallest skyscraper west of the Mississippi River when construction was finished; it is currently fourth by that metric, the second tallest building on the West Coast, and the one of the tallest building in the United States. It contains 76 stories of office space above ground and seven stories of various use below ground, making it the building with the most stories west of the Mississippi.

The base of the building is clad in Rosa Purino Carnelian granite, giving the building an elegant appearance. The building’s structure is composed of three geometric arches, causing the building to appear like three towers standing side by side. (The tower was originally designed to be about 306.5 meters tall, but federal regulations by the FAA would not allow it to be that tall so close to the nearby Sea-Tac Airport.) There is an observation deck on the 73rd floor which offers views of Seattle. The top two floors of the building (75th and 76th) are occupied by the private Columbia Tower Club, which houses a restaurant, bar, library, and meeting rooms.
