Enjoy the photo essay (at least I got more than 3 photos LOL *muffled subtle jibe*)
The Mona Lisa, by Leonardo Da Vinci, behind a protective glass, surrounded by barricades. You can easily find your way to her by just following the general crowd movement. Everybody's favourite controversial chick.
And yup, my gut feel is that there will be a sequel to this movie - Angels and Demons (actually a prequel), but that's a photo essay for another two Cities, Rome and The Vatican, for another day :-D
