School classes and groups of 10 or more people
Please register school classes and groups of 10 or more people by telephone on +49 201 301040 before your visit. This will enable us to check whether any guided tours or events are already planned for the day in question. We also need to coordinate with the teaching staff in order to prepare for the admission, supervision and briefing of the pupils. Unfortunately, we cannot accommodate visits without prior registration.
