The Georgia Centennial Farm Program was created to draw attention to historic farms and to encourage their preservation. Nominees must be a working farm with a minimum of 10 acres actively involved in agricultural production or generate at least $1,000 in annual income. In addition, farms must be continuously farmed for at least 100 years and owned by members of the same family for at least 100 years or be listed in the National Register of Historic Places. Since starting in 1993, the program has recognized 359 farms around the state. Qualifying Centennial Farms are honored each October at a special award ceremony at the Georgia National Fair in Perry, Georgia.
