Bigger apparently isn't always better, at least when it comes to architectural beauty.

South Dakota's tallest building is also the state's ugliest, according to a new survey.

Business Insider asked readers to name the one local architectural blight they hate and in the Mount Rushmore State it was the CenturyLink Tower in downtown Sioux Falls.

The 11-story, 174-foot tall structure opened in 1986 and was originally known as the US West Tower. The name of the building has changed with each subsequent name change of the company it houses - becoming the Qwest Tower in 2000, before changing to CenturyLink in 2011.

The building, which was the second tallest in South Dakota before the Zip Feed Mill (202 feet) was torn down in 2005, even has its' own Wikipedia page.

The Century Link Tower shares its' eyesore label with some other well known structures across the United States - like the Denver International Airport in Colorado, Madison Square Garden in New York, and the Watergate complex in Washington DC.

The state capital buildings in Santa Fe, New Mexico and Bismarck, North Dakota also made the list.
