By 1861, it had taken 22 years and seven architects to complete the Ohio Statehouse in Columbus. Consequently, the final building did not resemble any of the original designs. For example, a classic dome had been specified. Instead, a low conical roof was built. One critic called it, “a Chinese hat.” Nor does the building follow any single architectural style, although it does have several Greek elements. During the next 128 years, the original 54 rooms were expanded to over 300. This crowded much of the lavish interior spaces. Its best features are the numerous historic paintings and sculptures. Ohio became the 17th state on March 1, 1803.
