Statue of Freedom

The Statue of Freedom, also known as Armed Freedom or simply Freedom, is a bronze statue designed by Thomas Crawford that, since 1863, has crowned the dome of the U.S. Capitol building in Washington, D.C. Originally named Freedom Triumphant in War and Peace, a U.S. government publication now states that the statue "is officially known as the Statue of Freedom." The statue depicts a female figure bearing a military helmet and holding a sheathed sword in her right hand and a laurel wreath and shield in her left.
