An example of meticulous town planning, Ferrara, City of the Renaissance, and its Po Delta 14 is an UNESCO World Heritage Site. The duke of the city, Ercole d’Este I was a music and art aficionado and he was the reason behind Ferrara becoming a center for cultural activities. Many eminent artists arrived here to showcase their talent, including veterans like Piero della Francesca and Andrea Mantegna whose paintings adorn the walls of Ercole d’Este's residence. River Po Delta, which is inseparable from the city's character, clearly lets one identify this ancient city's immaculate planning. Many Renaissance gardens, cathedrals as well as historic buildings were constructed here with painstaking importance to urban forethought. All of these are worth a visit, if you love art and travel.
