Unfairly ousted from the list of seven mythical hills of Rome due to its geographical location (west of the Tiber, thus outside the walls of Ancient Rome), the Janiculum takes vengeance on its illustrious rivals by offering the best view of the city. You don't come there seeking the protection of the deity Janus, who was worshipped here in ancient times, but for the breathtaking panoramic view.
Rome offers itself before your eyes, in all her stunning beauty. A sea of domes spreads out before you; can you recognise them? The grandest are Saint Peter's and the Pantheon; the others, barely more modest, are Santa Maria di Loretto, San Carlo al Corso, Sant' Agnese in Agone… It's impossible to count them all! The cannon fire you hear is the Pantheon's twelve o'clock gun. It is used to synchronise all the clock towers of the city, which, grateful, peal their response in unison. Tip: go back at night, when the spectacle is even more stunning.
