Cannon Rotunda
About this object The stately view from the Cannon Rotunda provided a well-composed scene for a tourist's picture postcard from the 1920s.
The coffered dome’s central skylight and the large windows along the second story flood the space with light. These double height windows, framed by gilded pilasters, create picturesque views of the Capitol and its grounds, a decorative device encompassing the intention of the Cannon building’s design, making explicit the visual connection between the two. Though the Rotunda is impressive, it is a reflection of its even-grander neighbor. Opposite the main entrance, a marble split staircase leads up to the marquee space of the building, the Caucus Room.
