When shooting in all the museums of the Vatican and St. Peter's Cathedral, it is forbidden to use tripods. In addition, it is forbidden to shoot with a flash, and in the Sistine Chapel any amateur photo and video shooting is generally prohibited. At the entrance to the Vatican Museums, a tripod and all bags-rucksacks must be handed over to the storage room. The disadvantage is that to get your things you have to leave the museum through the main entrance and once again hold out the queue of security control. It will be better if you leave everything superfluous in a hotel or a tourist bus.
