During the early part of the twentieth century, a new conception of design was emerging, called City Beautiful Movement. The existing buildings on the plaza, punctuated by the building of the Indiana War Memorial provided a formal setting with classical designs that reflected the concepts of the City Beautiful Movement. The War Memorial is inspired by a neoclassical design. It is similar to the Greek architecture of the fifth century, in particular the mauseoleum at Halicarnassus. It is a square shrine structure with a pyramidal dome, and has Ionic columns.
