On the corner of Columbus and Jefferson Streets in Ottawa, Illinois, there is a distinctive building made of red brick and Joliet Limestone. The architectural style is Classical Revival. This structure currently serves as the 3rd District Illinois Appellate Court. The central portion of the building was constructed between 1857–1860 at a cost of $230,000. The wings of the structure were added in 1877.
For years, the building served as one of the three Illinois Supreme Courts. The other two were located in Springfield and Mount Vernon. In 1897, the state consolidated the three courts into one located in Springfield. Since that time this building served as the 3rd District Illinois Appellate Court.
