After our visit to the Pantheon, we consulted the map and realized we weren't that far from the Trevi fountain. Off we went, but after a few circles were a bit confused. The map said it was to our left, but there was nothing there but a bunch of scaffolding, some plastic sheeting . . . and a large crowd of people . . . taking photos. We had stumbled across Trevi fountain but the whole thing was under renovation!
