The Shrine Room, with 24 stained glass windows, is a magnificent architectural setting for the 17-by-30 foot American flag that is suspended from the center of the room. The main floor houses exhibit space, administrative offices, meeting rooms and the Pershing Auditorium. Also on this level is a listing of the names of all Hoosiers who participated in World War I and all Hoosiers who were killed or are MIA from World War II, Korea and Vietnam.

A military museum in the basement allows visitors to follow the history of Indiana soldiers from the Battle of Tippecanoe through the most recent conflicts.
