CenturyLink Tower (formerly Qwest Tower) is a 296,448 sq ft (27,540.9 m2)[2] office building located in downtown Sioux Falls, South Dakota.

At 174 ft (53 m) and 11 stories tall, it is the tallest building in the state of South Dakota.

Previously, the 202 ft (62 m) Zip Feed Tower was the tallest building in the state.

The building has had two different facades; initially it was of white stone, but structural issues that soon developed forced US West (later known as Qwest) to remove the outer facade and later install the present exterior.
