anyone know if taking pictures is allowed in Musée de l'Armée in Paris?
From what I remember, you couldn't take a picture of Napoleon's tomb (although, everyone snuk at least one), but cannot recall the rest.
Are tripods allowed?

I have dozens of pictures from inside the museum. I don't recall ever seeing a sign not to photograaph. You might be restricted from using a flash

ah, that may be it; the flash!
thank you.

Not only a flash- but also a tripod. If people are taking casual holiday photos with a tiny camera they may not like it but you can usually get one of two., I thnk for a tripod you would have to apply in advance - and if approved, paya fee - as they would assume you're a professional photographer. After all, at tripod is a huge pain to other tourists trying to visit a sight.

(I'm always amazed at the tourists in NY who try to take photos of friends in front of some sight and expect everyone else to wait - or walk in a big circle around them, while they pose, snap, chat etc. I've even sen them ask people to stop while they shot photos - not that ayone wold of course.)

In the US the rule is usually like this: if an exhibit is permanent, no-flash photos are allowed. If it's something borrowed (traveling exhibit) photos are not allowed.

Is it something like this in most European countries?
