It is important to know that in order to reach the Ancient Center of the city is enough "just to turn the corner" entering in via S.Romano (pedestrian area with a lot of shops). You soon reach piazza Trento Trieste, just next to the wonderful Cathedral (XII century), the Estense Castle (year 1385), Corso Ercole I d'Este (architect Biagio Rossetti) with the magnificent Palazzo dei Diamanti, center of the National Picture-Gallery and site of important shows of modern art and all the Medioeval and Renaissance city.
