This grand showpiece square beautifully encapsulates the splendour of Venice's past and its tourist-fuelled present. Flanked by the arcaded Procuratie Vecchie and Procuratie Nuove , it's filled for much of the day with tourists, pigeons and tour guides. To get a bird's-eye view, head to the Basilica di San Marco's free-standing 99m campanile , which commands stunning 360-degree panoramas.
