Stone Mountain is a city in DeKalb County, Georgia, United States. The population was 6,703 according to the 2020 US Census. Stone Mountain is in the eastern part of DeKalb County and is a suburb of Atlanta that encompasses nearly 1.7 square miles. It lies near and touches the western base of the geological formation Stone Mountain. Locals often call the city "Stone Mountain Village" to distinguish it from the larger unincorporated area traditionally considered Stone Mountain and Stone Mountain Park. History Stone Mountain's history began long before European settlers and the Creek Indians before them. Evidence of numerous earlier Native American tribes, including mound builders, has been found in the area. The Treaty of Indian Springs in 1821 opened a large swath of Georgia for settlement by non-Native Americans on former Creek Indian land, including present-day Stone Mountain Village. In 1822, the area that now makes up the city was made a part of the newly formed DeKalb County. Settlement By the 1820s, Rock Mountain, as it was then called, was "a major travel center", with an inn for travelers. A stagecoach line linking the village with Georgia's capital, Milledgeville, began in 1825. Another stage line ran to Winder and Athens. In 1828 another stage line began trips to Dahlonega, and a fourth connected the community with Macon. "Hundreds of people visited Rock Mountain in the summer [of 1828] and...a house of entertainment was nearby." Rail service did not reach the town, by then New Gibraltar, until 1845. A post office was created in 1834 on the old Augusta Road, and Andrew Johnson, called the founder of New Gibraltar and first mayor, around whose house the city limits were drawn, built a hotel along the road in 1836. ("An 1843 amendment to the act of incorporation extended the town limits to in every direction from the house of Andrew Johnson.") About 1839 Aaron Cloud, who also had a hotel, built a wooden observation tower, octagonal like a lighthouse and high, along with a restaurant and club, at the mountain's summit. A storm destroyed the tower in 1849; in 1851, Thomas Henry built a smaller, tower, with telescopes so it could serve as an observatory. Visitors to the mountain traveled by rail and road, then hiked up the mountaintop trail to the top. By 1850, Stone Mountain had become a popular destination for Atlanta urbanites who endured the four-hour round
