To represent the District of Columbia and to authenticate certain documents.
The Seal of the District of Columbia consists of a circular design with the words “DISTRICT OF COLUMBIA” stretched across the top inside portion in an arc. The Seal includes two human figures which are the likeness of George Washington and a blindfolded female figure holding a wreath in her right hand and a stone tablet with the word "CONSTITUTION" in her left hand. The Seal also contains a depiction of the United States Capitol, several agricultural products, an eagle in a war stance, a train locomotive crossing the Potomac River, emblazoned by a radiating sun and trailed by several rail cars. The seal reads the motto of the District of Columbia, "JUSTITIA OMNIBUS" (Latin for "justice for all"); and "1871" (the year when the District of Columbia Organic Act of 1871 was passed, organizing the District in its present form). The official seal is always presented in black and white. The Secretary of the District of Columbia is the official custodian of the Seal.
This collection of United States Seals was registered by the Library of Congress in 1876. When enlarged, the Seal of the District of Columbia has one noticeable difference: the space now occupied by George Washington is held by the Statue of Freedom.
