This was an impromptu stop after a friend drove us to the giant wine store in Castelfranco; we were on our way back. He said let's look at the city inside the wall.
When you do, you get Cittadella. I'd like a dozen more stops here. To walk the wall. To stare at the moat. (Yes, a real moat with water surrounds this entire place.) To stop for snacks. To notice more of the odd little windows in circles and rectangles, more I've noticed here than anywhere else.
But there are always more stops to make.
