Like a remnant of some forgotten Cecil B. DeMille movie-set, the massive late-19th-century Vittorio Emanuele monument -- -the "eighth hill of Rome" -- looms over the geographic center of the city, the Piazza Venezia. Just to its south rises the Campidoglio hill, crowned by Michelangelo's magnificent piazza and the Capitoline museums. Below them extends the most evocative ruins of the ancient city: the Roman Forum, bookended by two great triumphal arches, the Arch of Constantine and the Arch of Titus. Beyond Titus's monument lies the fabled Colosseum and the Baths of Caracalla.
