In the cathedral and castle of this jewel of urban living and architecture, one of the borghi più belli d'Italia, can be found some of the most important symbols. The old manor, where Napoleon was also a guest, "stands guard" over lanes and houses that maintain intact their splendour. Of value is the 16th century monumental organ present in the Cathedral. In mid-September it is possible to relive the medieval atmosphere during the historic commemoration.
