The shape of the building is a large 150 foot Greek Cross. From the ground to the top of the statue, the building measures 226 feet.
Indiana limestone and brick were used for the construction of the walls. Cast-iron beams and supports, as well as the finest woods were used.
The Courthouse has one hundred columns, nine pieces of statuary and a cast iron dome containing four large clock-faces and a bell.
The statue on top of the dome stands 14 feet high, is hollow inside, and made of sheet metal. The original specifications for the Courthouse described the statue as the Goddess of Liberty, holding a shield and sword. Some people believe that the statue was meant to be a statue of Justice, holding a set of scales. The statue is now holding scales that were found in the clock tower during restoration.
