Please do not be put off by the comments about Petrarch's house! It is a beautifully preserved building, and yes, it does have photos and information on the history of the town...isn't that the point of a "historical" landmark. And if you time it right, you can get in free (certain days, not sure of timing). We were there the first weekend in October 2007; it was a celebration of the European Heritage Festival and organic foods festival, and it was wonderful. Don't miss this place-it has not changed much since the 1300s in terms of it's look.
We climbed the numerous steps indicating another war memorial, which every town has of course, not to view this monument 'for the fallen soldiers' so much as to gain higher ground from which to see the countryside.
This appears to be the locals 'make out' place, as young couples were lip locked in an unashamed embrace, with no feeling of need to separate as we approached.
Great views of the country side from this vantage point.
