Have you ever taken a photo where no photography is allowed?

I have visited quite a few places in the world where photography is strictly prohibited (in fact most Cathedrals and Churches in Europe apply that rule). But, of course, there are many other places where they would rather have you buy the 'official postcard' of the monument, statue, or shrine, than take your own photograph. In almost every place where I have seen a 'no photography allowed' sign I have seen people trying to take photographs! And now, with the advent of Cell phone Cameras it is even worse!

Well, here's a site dedicated to pictures taken in places that prohibit photography.
