The Atlanta Constitution Building, also known as the Georgia Power Atlanta Division Building, is located at the northwest corner of Alabama and Forsyth Streets in downtown Atlanta, Georgia, at 143 Alabama Street, SW. It is located in an area known as the "Heart of Atlanta" straddling the railroad gulch ("The Gulch"), "due to [its] proximity to the 'Zero Mile Post' which marked both the Southeastern terminus of the Western and Atlantic railroad and the city's earliest settlement".
