United States Capitol rotunda, Neoclassical dome in Capitol Hill, United States.
The circular hall stretches 96 feet in diameter and rises 180 feet to the top of its cast-iron dome with sandstone walls and marble flooring.
Construction began in 1818 under architect William Thornton's design, with Charles Bulfinch completing the central rotunda structure by 1824 after war delays.
The rotunda exhibits historical paintings by John Trumbull depicting American Revolution events and the Apotheosis of Washington fresco by Constantino Brumidi.
The space connects the House of Representatives through southern corridors and the Senate chambers through northern passages within the Capitol building.
Presidents Abraham Lincoln and John F. Kennedy, along with civil rights leader Rosa Parks, have lain in state within this ceremonial chamber.
