The curators of the Marietta Museum of History honor the heritage of Marietta and Cobb Counties with educational events, rotating exhibits, and four specialized galleries that focus on different facets of Marietta tradition: home life, general history, the military, and the Civil War Union Raiders. Since 2000, museum staffers have hosted more than 90,000 visitors, guiding groups past Native American artifacts and antiquated industrial machinery in the General History gallery and navigating a 15.5-acre aviation park filled with civilian and military aircraft manufactured in Marietta. Guns, shells, and uniforms line the cases in the Military gallery, which elucidates the stories of the Civil War, World Wars I and II, and Vietnam, among others. The museum’s special exhibits rotate several times a year, with themes such as Y’All Come Eat: Exploration of Southern Food Ways, which features the nation’s largest display of antebellum macaroni costumes. Visitors can drop by Monday–Saturday, or pick up a membership to receive a newsletter and special invitations.
