The main levels of Iowa's Old Capitol have been restored as a museum and historic landmark, accurately depicting the time in which it served successively as a territorial and state capitol. Because of its statewide and national significance, and because the furnishings in the building are made up largely of antiques and other historic artifacts, Old Capitol is not a general-purpose meeting facility. Its uses are restricted to: tours by the general public and groups; meetings by groups with state, academic, cultural, or historical purposes, and by units of state government; and University operations housed on the building's lower level. Appropriate meetings in Old Capitol are held only in the Senate Chamber, and are restricted to the hours the building is open. Examples of meetings which would be considered appropriate to the Old Capitol are constitutional conventions, Supreme Court hearings, the defense of doctoral dissertations, faculty meetings, and workshops in historical preservation and restoration.
