Here is St. Maria di Fiore in Florence (I like to say Firenze). This was once the tallest church in the world, until of course, St. Peter's came along. Inside I cant recall why but it was seemingly empty, nothing about its interior was so captivating or anything, but the outside... that was a beauty of a basilica. Just the walls seemed 15 or more feet high. As you can see, it was currently under renovation or something like that :D.
