The two things that you can be assured of when visiting the Vatican are that you will see (1) some of the most amazing art and architecture and (2) lots and lots of domes. I am not sure which dome this is (if anyone recognizes this, let me know its name) but I just fell in love with the mural in it. Even though the colors are fading a bit around the edges, it still is beautiful. Shooting at the Vatican can be challenging with all of the crowds and not being able to shoot with a tripod.
