Few world cities hold the romance and historical sweep of Venice. Thousands visit every year - and a mixture of crowds and climate leave it vulnerable, so much so it is often said to be in danger of sinking - but away from the usual tourist haunts around St. Mark's square are exceptional hidden treasures, some 500 gardens, many of them with fascinating stories. Starting in the heart of the city and working their way out to the Veneto, Monty and Derry celebrate the beauty of these places and tell their unique stories: from a beautiful nunnery garden with a history of exotic animals and a kitchen garden of the historic Foundation to the Madonna church to the estates of famous Venetian families, like the spectacular Giusti Renaissance garden.
