Take time to see the complex work of building this tower, with lots of details, it's well preserved history. Don't miss the church next door, it's free to visit, just make sure you get tickets across the street first. We went in late November, so it was cold and it was raining, but there were fewer crowds. At least in the off-season, you won’t need more than an hour or two to stay, but after that you can spend some time walking around town and experiencing the real Tuscany, where you can find a great pizza and ice cream wherever you go.
