Grand Army of the Republic Hall

The Grand Army of the Republic Hall is an octagonal limestone building on Stolp Island featuring Gothic Revival design with high ceilings and pointed arches throughout its interior spaces. A distinctive side tower was added in 1904 and remains a defining feature of the structure's exterior.

The structure was built in 1877 and served as a meeting place for Aurora G.A.R. Post No. 20, where more than 600 Union veterans gathered until 1947. This location became a center for veteran administration and community bonds in the years following the Civil War.

The building functioned as Aurora's first free public library until 1903, serving as an important gathering place where residents could access books and educational materials. During those years, the rooms hosted community members seeking knowledge and cultural enrichment.

The museum is open Wednesday through Saturday for visitors and is located at 23 East Downer Place in Aurora. Allow plenty of time to explore the exhibits about veterans and military heritage displayed throughout the interior.

The limestone structure follows the design of a brick memorial hall in Foxborough, Massachusetts, yet remains the only known work by architect Joseph Mulvey. This makes it a rare example of his architectural legacy.
