Grantville is a city in Coweta County, Georgia, in the west-central part of the state, southwest of Atlanta and near the county seat of Newnan. At the 2020 census, the city reported a population of 3,103. Grantville grew as a railroad and cotton town in the late 19th century, when the arrival of the rail line brought commerce and industry to the community. Cotton was king, and the town's historic downtown, largely built in the late 1800s, preserves the scale of that era. The Grantville Historic District, listed on the National Register of Historic Places in 1991, encompasses more than 200 contributing buildings — one- and two-story brick commercial structures and homes — centered along the railroad corridor and bounded by U.S. Route 29 and the city cemetery. The community was also home to the Grantville Hosiery Mill and Grantville Cotton Mill, which anchored the local economy until their closure in 1980. In recent decades, Grantville has become known for its well-preserved historic downtown, which has served as a filming location for television productions, including scenes for "The Walking Dead." The city is a stop on the West Georgia Textile Heritage Trail, which interprets the region's mill and manufacturing history. Grantville has experienced population growth driven by its proximity to Atlanta and the broader Coweta County area, while retaining its small-town, rural character. Public schools in Grantville are part of the Coweta County School System, including Glanton Elementary School within the city. Grantville appeals to families and residents seeking an affordable small-town setting with historic character and convenient access to Newnan and the Atlanta metropolitan area.
