Are there things, which are not allowed to bring with me ?

Yes. No kind of bottles, cans, alcoholic drinks, animals, fourniture, drugs or similar, no weapons or anything that can cause harm to yourself or others. This list could be endless, we urge you to use common sense. It is not allowed to bring video cameras or equipment for recordings. It will be ok if you bring an ordinary pocket camera that can not be used for recordings, no digital or system cameras.
