The rotunda is connected by corridors leading south to the House of Representatives and north to the Senate chambers.
It is also used for ceremonial or public events authorized by concurrent resolution of both houses of congress, including the lying in state of honored dead.
However, due to lack of funds or resources, oft-interrupted construction, and the British attack on Washington during the War of 1812, work on the rotunda did not begin until 1818.
The rotunda was completed in 1824 under Architect of the Capitol Charles Bulfinch, as part of a series of new buildings and projects in preparation for the final visit of Marquis de Lafayette in 1824.
In 1862, Walter asked painter Constantino Brumidi to design "a picture 65 feet (20 m) in diameter, painted in fresco, on the concave canopy over the eye of the New Dome of the U.S. Capitol".
Visitors can still see the holes in the stone circle that marked the rim of the open space in the rotunda floor.
The Apotheosis of Washington is a large fresco by Greek-Italian Constantino Brumidi, visible through the oculus of the dome of the rotunda.
While working on William Penn and the Indians, Brumidi fell off the scaffolding and held on to a rail for 15 minutes until he was rescued.
A statue of George Washington – a copy after French neo-classical sculptor Jean-Antoine Houdon's 1790 full-length marble in the Virginia State Capitol – holds a prominent place.
Sculptor Niehaus returned to America in 1881 and by virtue of being a native Ohioan was commissioned to sculpt a monument to the recently assassinated President James Garfield, who was also from Ohio.
Because the bust would be such an important and visible work of art, the Joint Committee on the Library decided to have a national competition to select a sculptor.
"[citation needed] John Woodrow Wilson, the artist was awarded a $50,000 commission to cast the model in bronze.
The portraits are copies of the individual busts she carved for the Court of Honor of the Woman's Building at the World's Columbian Exposition in 1893.
Contrary to a popular story, the intention was not that it be completed upon the ascension of the first female President — the rough-hewn section is too small to carry a proportional bust.
The monument was presented to the Capitol as a gift from the women of the United States by the National Woman's Party and was accepted on behalf of Congress by the Joint Committee on the Library on February 10, 1921.
The unveiling ceremony was held in the Rotunda on February 15, 1921, the 101st anniversary of the birth of Susan B. Anthony, and was attended by representatives of over 70 women's organizations.
Sculpted by David d'Angers, it was donated by Uriah P. Levy and is the only work of art in the Capitol given by a private donor.
