 The three finished interior floors have been renovated , modernized , and updated since the original construction . One step in modernization occurred in 1965 , when an elevator was installed in the building . Among various renovations , the second and third floors were updated around 1980 . Currently , the first floor has carpeting , fluorescent lighting , and acoustic ceiling tiles . The north and south facades now have modern glass doors that form vestibules at the entrances . The hallway ceilings have been molded with stenciling . Some painted scenes , which are not original to the building , can be found in the main hallway . One such scene includes a painting of the original courthouse surrounded by paintings of tablets representing each of the county 's four townships , each with local scenes .
