a low conical roof that some critics would deride as "a Chinese hat." Construction of Capitol Square, including its buildings, grounds, and landscaping, was finally completed in 1861. Changes and expansion As the function of state government changed and expanded, changes and expansions occurred at the Ohio Statehouse. Originally, the building was the main location for all aspects of state government. As more offices and work rooms were required, large spaces would be subdivided into smaller areas. The most prominent example was the conversion to offices of the four open courts that occupied areas on the interior of the building. These open areas were from top to bottom of the structure and were intended to admit light and fresh air to the inner reaches of the building. The advent of electric lighting coupled with the need for space meant that levels of offices would come to occupy these large open areas. The fifty-four rooms the building originally held increased to 317 rooms by 1989. In 1901, facing significant crowding several changes were considered including a completely new statehouse designed to more closely resemble the national Capitol building in Washington. Cost prohibitive, it was decided that the Ohio Supreme Court would move to a separate building on the east side of Capitol Square, and to give the court the prestige of its own building. The new building, named the Judiciary Annex, was constructed of the same Columbus limestone as the Statehouse. Neoclassical on the exterior, the interior spaces, especially the grand central staircase are Beaux Arts in style. The building was the work of Cincinnati architect Samuel Hannaford, and was completed in two years at the cost of $375,000. By comparison, the Statehouse itself took 22 years from start to finish and cost approximately $1.3 million. The difference in cost and time to completion indicates differences in how the buildings were constructed. The Statehouse is more akin to a castle or cathedral, with thick load-bearing walls of stone. The Annex was a modern building with a metal girder skeleton and was planned for the use of electric light. The building retains many of its original light fixtures, while those in the Statehouse are reproductions of the gas lights that were removed to make room for electrical appliances in the 1890s.
