 Behind right and center field, atop the slope bordering the park on the East, were the tracks of the Southern Railway, now part of the BeltLine, a trail and future transit ring around the central neighborhoods of Atlanta.Across the street was the Ponce de Leon Amusement Park until 1926, when the hulking Sears Roebuck Southeastern Headquarters, now known as Ponce City Market, was built.The original ballpark on the site opened in 1907.
