Important hygiene & safety regulations for your visit: • Please visit us only, if you are completely healthy! This is especially important in the current cold season. Please stay home with cold symptoms out of consideration for our other visitors. • All guests are asked to wear an FFP2 mask in the elevators in the exhibition and during the site tour. Wearing an FFP2 mask is only recommended beyond that. • Our visitors must keep a minimum distance of 1.5 meters throughout their visit, avoiding the formation of groups. • In addition, the hygiene tips from the Federal Center for Health Education (as signposted on site) apply.
