No admittance for groups without prior booking, with or without guide
The following people are authorised to address a group, on mandatory presentation of supporting documents to the information officers:
Anyone wishing to address a group as part of a visit and not falling under any of the above categories must submit a written request for authorisation to the Director of Visitor Services, at least one week prior to the visit date.
The person authorised to address a group may not transfer this authorisation to any other member of the group.
This authorisation expires at the end of the allocated time slot. A visit time slot only authorises one speaker for one visit.
Students and pupils are authorised to address their peers as part of university or school tutorial classes as of upper secondary school level.
It is mandatory to wear a visible card, whether the guided tour is for fewer than 7 people or for a group.
Guided tours are prohibited on Sundays and public holidays.
