Via Veneto, center of "La dolce vita", Piazza Barberini with the Triton Fountain by Gian Lorenzo Bernini; Piazza Venezia and the gigantic Vittoriano Monument. Then Via dei Fori Imperiali towards the Coliseum, the Arch of Constantine, the Palatine Hill, the Temple of Hercules, the Theater of Marcellus, the Capitol, the Tiber Island, the Roman Synagogue, Castel Sant'Angelo and, finally, St Peters and the Basilica and the Vatican Museums with the Sistine Chapel.
Ending at the Trevi Fountain, the Pantheon and Piazza Navona. Is there really anything more marvellous all in one place on this earth.
