Whether visiting with an official guide or not, you are expected to ensure that your group is following the museum rules and regulations. Visitors are not allowed to touch the artworks or shout or run in the museum.
Speaking to the group in the Salle des États and stopping with the group in the side corridors is forbidden, to avoid blocking room access. It is possible to cross the room without stopping as a group; and group tour participants can freely return to the room on their own following the guided tour.
