The Clarksville Historical Society (CHS) was founded by former town councilman Bob Popp in April of 1996. A room in the Clarksville Municipal Building was set aside as a museum of town history. A collection of items from an earlier museum, sponsored by the Clarksville JayCees, was the nucleus of the present collection. Currently, a collection of artifacts, documents, maps and photographs obtained over the past 20 years are cataloged and housed in the museum.

The Society founded and hosted the Lewis and Clark Bicentennial Commemoration for 6 years at the site where the famous expedition began, and were partners with the Falls of the Ohio State Park in the placing of the replica cabin at the George Rogers Clark Homesite at the Park.

In addition, the Society spearheaded the building of the War Memorial on the campus of the Clarksville Municipal Center. A place of quiet reflection and/or celebration of our men and women who have served. The CHS also sponsors a Veterans Day and Memorial Day service at the Clarksville War Memorial.

​The Society meets monthly from March through November, and publishes a newsletter during that same period. From the original 12 members, the society has grown to more than 150 members in 8 states.
