United States Capitol rotunda

The Capitol rotunda is a large circular hall with cast-iron elements, sandstone walls, and marble flooring beneath a tall dome. The space connects the north and south wings of the building and serves as a central gathering point with decorative frescoes and historical paintings on walls and ceiling.

Construction started in 1818 and took several years until the central hall was completed in 1824. The cast-iron dome was added later in the 19th century, replacing an earlier wooden structure.

The ceiling displays a large fresco where George Washington appears among allegorical figures, surrounded by scenes of science and industry. Visitors can also view large paintings on the walls that depict moments from the founding era of the nation.

The hall is accessible through several entrances in the Capitol building and forms part of the publicly accessible areas during regular opening hours. Visitors should note that security checks are conducted at the entrance and access may be limited during special events.

The ceiling holds 180 tons of cast-iron work installed during the 1860s amid the Civil War. Some of the artworks in the hall were originally intended for other locations and were brought here only later.
