Visits: access & bookings

There are two main areas involved in a visit to the Data Centre:

  • The Gallery and Museum.
  • The Data Centre VisitPoint permanent exhibition.

Reservation is compulsory for any visit to the Data Centre areas in order to avoid tour-group clashes, and also to respect fire hazard/safety limits in these zones.

Room availability

The availability calendar for the room can be consulted here:

Opening hours

  • Monday: 10am - 7pm
  • Tuesday to Friday: 8am - 7pm
  • Saturday: 9am - 5pm

Please note that when a group is in the DCVP, a red light is displayed above the door in the corridor outside to indicate the room is occupied. The red light goes out only when the sensors in the room do not detect any movement for five minutes (ie. after a group has left). A ‘grey’/off light will indicate the room is empty.

  • Please see the noise protection regulations if guiding in the Data Centre itself.
