Treviso is a very old town near Venice. I asked very much people why this city has that name and they told me Treviso mean 'tre visi' ital. for three visites. I think it's cause of the three rivers going through the town.
Favourite spots:
nearly everything. The best you could do is to take a tour guide but the nicest places are along the rivers ... there it looks a little bit like Venice ( cause many years ago Treviso has belonged to Venice
What's really great:
the 'Duomo' the cathedral is very beautifull but also the advice house
Sights:
Via and Canale della Roggia
island with fish-market
