The Grand Army of the Republic Hall is an historic building located at 23 East Downer Place on Stolp Island in Aurora, Illinois, in the United States.

White was inspired by a recent visit to Memorial Hall in Foxborough, Massachusetts, and noted that that structure was a useful meeting place and library.

The building was constructed on Stolp Island, a small piece of land considered to be "neutral territory" between the east and west sides of Aurora.

Public outcry forced the city to change its plans, and a 1963 fundraising campaign provided financial support to rehabilitate the building.

The standing Gothic Revival structure is one and a half stories and features a small lot outside of the building with an 1851 cannon, a bench, and a flagpole.
