The DuPage County Historical Museum is housed in what was formerly known as the Adams Memorial Library. The building was erected in 1891 by John Quincy Adams as a gift to the community of Wheaton in memory of his late wife, Marilla Phipps Adams. Designed by Charles Sumner Frost in the Richardsonion Romanesque style, the building was added to the National Register in 1981. In the 1960s the DuPage County Historical Society recognized the availability of the building as a new and more spacious library was being erected. In 1967 the building opened as the DuPage County Historical Museum.

The Museum functions as the only institution dedicated to the collection, preservation and interpretation of the material culture documenting the county of DuPage, Illinois. The collections represent artifacts collected by the DuPage County Historical Society since 1929 as well as artifacts collected by the Museum since its founding in 1965.
