Citta di Roma
edit to add that this shot is taken from the observation balcony at the top of St. Peter's Basilica. Immediately in front is St. Peter's Square. The round building at the end of the street, to the left, is Castel Sant Angelo, shich was built as a fortress for Hadrian, I think, but taken over by the vatican as a place to hole up the pope during times of invasion. There are secret passages from Vatican City to the castle.
Immediately behind the castle is the justice building in my next pic.
If you look at the further bridge, and follow a straight path to the right, you can see the dome of Pantheon.
Kind of keep going in the same direction, but slightly upward and you can see Vittoriano. The monument in my last pic.
