The center room in the Ohio Statehouse is the Rotunda. In the top of the dome, a glass skylight is 120 feet above the marble floor. The center of the skylight shows the 1847 version of the Great Seal of the State of Ohio which included a canal boat. It is a replica of the skylight as it was in 1861, when the Statehouse was completed. This 1990's replica was paid for by Ohio schoolchildren, a penny at a time.
