Groups (including schools) composed of more than 10 people are required to book the Museum entry to get access to reduced admission fees as reported in the page tickets.
In particular circumstances it is possible to book an out-of-hours visit.
Groups can autonomously visit the Museum or use the offered guided tour service.
Some rooms are of small size. Museum personnel might request the group to split into subgroups in order to facilitate the visit and don't obstruct other visitors.
