Information on ticket refund

Dear visitors,

the ticket return form is currently no longer available. Please direct inquiries about your ticket booking and any changes to our visitor service.

Visitor service

The box offices in the visitor service are open again:

Monday-Friday 12.00-6.00 pm
(modified opening hours until the end of July 2021)


For this event, you will not receive tickets through our webshop. You will therefore be redirected to an external page of the organizer. If you have any not completed bookings on, they will be dissolved after 20 minutes.
