And looking the other way, you get what they say is on of the best public spaces in the world... Piazza del Campo. I'd love to go back on a day when I was shivering to death. However, the lack of tourists was nice.
I like the lighting... it's a grand view of what looks like an ancient city. Interesting that the architecture of the Pilgrim Tower in Provincetown on Cape Cod is very similar to the tower in your shot.
