Small, cute, good town to visit if you want to chill. There are one or two shops worth visiting and there's a couple of great restaurants too. Not much walking though and 2-3 hours is enough.
Da vedere: Porticciolo vecchio, Piazza Malvezzi, Duomo, Chiostro di Santa Maria de Senioribus, Museo civico archeologico Giovanni Rambotti, VillaRomana
