DuPage County Historical Museum is at 102 E. Wesley St. Housed in an 1891 Richardsonian Romanesque building, the museum highlights more than 150 years of DuPage County history with three floors of exhibits. Most areas of the museum include hands-on activities, and exhibits change frequently. An extensive HO gauge railroad layout on the lower level depicts the development of local railroads.
Guided tours are available by appointment. A guided architectural walking tour of the historic district also is available seasonally.
