1. There are no tourist crowds.
You won’t have to fight your way through clusters of loud groups consulting maps to see places like the elegantly built Chiesa di San Barnaba. In fact, you can just wander into most of Mantua’s sights (with the exception of Palazzo di Te and Palazzo Ducale) without even paying a fee. Plus there’s no tacky souvenir shops in sight and the only language you hear on the streets is Italian.
