The dome is painted with twelve different colors. Its skylight measures 29 feet.
A hand-painted Great Seal of Ohio crowns the rotunda.
Stretching 120 feet from the floor to the skylight, the Statehouse Rotunda is by far one of the grandest spaces in the Statehouse.
The rotunda is located below the cupola, which is itself an architectural feature unique to Ohio's Statehouse.
The cupola is the two-story, drum-shaped pinnacle with a low conical roof. The rotunda ceiling is 67 feet lower
than in the United States Capitol Building in Washington D.C.
Pete Fact : The cupola drum is 70 feet tall and 64 feet across and the height from the pinnacle of the cupola to the
rotunda floor is 158 feet.
A 29-foot-wide skylight crowns the rotunda. The skylight features a hand painted image of The Great Seal of Ohio in the center. First designed
in 1847, the state seal has changed several times in the course of Ohio’s history. Mountains, a sheaf of wheat, and a bundle of arrows are depicted
in the current state seal. The 1861 seal, which is displayed in the rotunda skylight, also includes a canal boat in the foreground. Canals were an
important mode of transportation in Ohio at the time.
The rotunda's intricate tile floor is composed of more than 5,000 pieces of hand-cut marble from around the world and holds rich symbolism. The salmon
stones are from Portugal; the black and green marble is from Vermont; and the white marble is from Italy. The thirteen center stones represent the original
colonies. The three marble bands represent the three major phases of the United States' growth across the continent prior to the floor design in 1858. These
include significant territorial expansions following the American Revolution, the Louisiana Purchase and a series of events after 1846 – the Mexican War,
the Oregon Settlement and the Gadsden Purchase.
