If, you ever get a chance, you should one day appreciate the splendid display from the Gianicolo's belvedere and suddenly hear a loud gun shot, do not be alarmed… just check your watches because it will be midday! Since 1847, on the orders of Pius IX, a special gun fires blanks around early afternoon at the top of the hour. Starting from by means of Garibaldi you can arrive at the highest point of the Hill with a 20-minute stroll across the Passeggiata del Gianicolo and come to the "Belvedere", an impressive porch located in Piazzale Garibaldi.
