Maybe it depends on the country. I know Canada isn't in Europe, but as an American citizen I have casually wandered onto Canadian military bases before without any hassle. Sometimes they have guards at the gate that ask to see your ID then wish you a good day, but other times there is nobody at the gate and you're free to wander around. Incidentally the Royal Canadian Artillery Museum has a superb collection. This all contrasts sharply with my experiences visiting American military bases, where the impression of security/paranoia is in my experience quite high, even though I was visiting somebody who lived there and he'd told them to expect me.
