Twice a year Northwestern Georgia celebrates its cultural traditions on the grounds of a historic water-powered mill. The Prater Mill, located on the Coahulla Creek, was built by Benjamin Franklin Prater in 1855. During the Civil War, the mill was used as a campsite for soldiers on both sides. Since it was considered an important source of food, it was not destroyed. The Prater family operated the mill until the 1950s.
