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 its current location in Monmouth in 2009.

Over the years, we have collected and preserved items that represent the history of our county and those who have lived here. The tradition of preservation and exhibition continues today as we work to save and document our history and share this knowledge with the public.

Thanks to funding from the Pattee Foundation, the Museum was able to hire a full-time director in 2016 in order to better serve our community. We continue to grow and expand, always following our mission of preservation and education in order to safeguard our history for the future.
