The Warren County History Museum focuses on the extensive history of Warren County Illinois since it's inception in 1825. We feature exhibits that examine the agricultural, industrial, educational, and military history of the county and its residents.


The Warren County History Museum strives to collect, preserve, educate, and display historical items, structures, monuments, and landmarks related to Warren County, Illinois.


Originally founded in 1968, the Warren County Historical Society was headquartered in Roseville, Illinois. The original museum was organized in the Roseville High School building, opening to the public in order to share the historical legacy that was collected by county residents. Over time, the Roseville High School building began to fall into disrepair, causing the collections to be put at risk.

In 2008, with the help of local philanthropic organizations, the museum was moved to its present location in Monmouth, Illinois. Since moving to our new location, the museum has continued to expand and increase its visitorship and reach within the community. Today the museum creates exhibits and programming that focus on local history and its relation to the modern day.
