File:Lady Wisconsin.jpg
Initially the statue of Wisconsin on the top of the dome was promised to Helen Farnsworth Mears but when Daniel Chester French agreed to produce the finial figure, the commission was switched to him. This work, often referred to as the "Golden Lady," consists of an allegorical figure reminiscent of Athena, dressed in Greek garb, her right arm outstretched to symbolize the state motto, "Forward", and wearing a helmet topped by a badger, the Wisconsin state totem. In the left hand it holds a globe with an eagle perched on top. Across the eagle's chest is a large W, for Wisconsin, a detail not visible in the photo.
Note the security camera added somewhere between 2006 and 2011.
