Visits are possible Monday to Saturday from 9h00 until 18h00. For all enquiries or to reserve a guided tour of the CMS site please send an e-mail to CMS Visits at least a week in advance (1 month for larger groups) of the tour date, indicating your preferred date, time and the number of people in the group (maximum group size 48 people).

We look forward to welcoming you to CMS.
