I think this is Piazza Republica. One of my all time favourite night shots taken from the top of the bell tower by the Duomo. I really wasn't sure how well it was going to come out since I was shooting a very long time exposure on the precarious edge of a small window with the bells gonging up a storm. I was amazed by the level of shadow detail on the rooftops that turned out. Lens: 50mm.
