The Cannonball House, named for damage sustained in the Civil War, is a Greek Revival Structure dating to approximately 1853. The house contains period furnishings, contents of the founder's parlors of the ΑΔΙΙ and ΦΜ societies, and a collection of Civil War era artifacts. A two-story kitchen house in the back, once the quarters of the family servants, is one of few such surviving structures. Collection highlights include Civil War uniforms, early 1800s face shields, and a circa 1850 Bohemian crystal punch bowl.

The house offers period rooms; exhibits; tours, which can be customized to educational needs and focal topics; educational programming designed to meet state educational criteria; demonstrations at special events; and a December children's Victorian tea party.
