If, per chance, you should one day be enjoying the splendid panorama from the Gianicolo’s belvedere and suddenly hear a loud cannon-shot, do not be alarmed…just check your watches because it will be midday! Since 1847, on the orders of Pius IX, a special cannon fires blanks at noon on the hour. The pope wanted to set a standard time for all the bells of the Church of Rome so that they would chime at the same time. Since 24 January 1904, the cannon has been firing at the top of the Gianicolo from under the statue of the Italian Patriot and Hero of Two Worlds Giuseppe Garibaldi and its shot. When the city is little less noisy, it may even be heard from the Esquilino Hill.
