The Voices of Veterans theaters provide more detailed accounts of experiences by Iowans. The theaters in the lower level areas feature historical reproductions about the activities of specific units: the 21st Iowa Volunteer Infantry, the 51st Iowa Regiment and the 168th Iowa Regiment, part of the Rainbow Division. The productions have been drawn from letters, diaries and historical accounts. The upper level theaters feature the voices of actual veterans through video interviews, which capture the emotion and pride they experienced.
