Warren County History Museum

238 South Sunny lane
Monmouth, IL 61462


The Warren County Historical Society was founded as a non-profit in 1968 and opened its museum in 1970 in the old Roseville High School. After 38 years in Roseville, the museum moved to our current location in Monmouth in 2009. Over the years, we have worked hard to collect and preserve the historical items that represent the history of our county and those who have lived here. The tradition of preservation and exhibition continues today, as we constantly work to save and document our history while sharing this knowledge with the public. In 2016, the museum first opened its doors for regular business hours in order to better serve our community. We continue to grow and expand, always following our mission of preservation and education in order to help create a better, more prosperous community.
