1 / 40
Atlanta's federal penitentiary, among the original three authorized nationwide through the Three Prisons Act of 1891, remains one of the city's unique historical landmarks. The other two prisons established were USP Leavenworth (Kan.) and USP McNeil Island (Wash.). USP Atlanta remains in operation as a medium security location. This is the old penitentiary entrance, photographed in 1910. GEORGE GRANTHAM BAIN COLLECTION / LIBRARY OF CONGRESS
