Flat Rock is a historic African American community in DeKalb County, Georgia. It is located within the city of Stonecrest, as well as the Arabia Mountain National Heritage Area. Flat Rock is believed to be one of the oldest African American settlements in DeKalb County. In 1820, the area rested along the border of Creek and Cherokee Nation hunting grounds when it was settled during the Georgia Land Lottery. In 1865, after the end of the Civil War, the era of reconstruction provided opportunity for former enslaved people to stay in the area to build schools, churches, and civic organizations and create the tight knit African American Flat Rock Community. The community has continued to live in the area and have experienced the Black Codes, Jim Crow and the Great Migration. The area currently houses the Flat Rock Archives, which specialize in preserving African American rural history in Georgia.
