We apologize for any inconvenience caused, but we are not allowed to change or refund bookings once confirmed, even if these were not used. The rules of the ticketing service are defined by the museum, and they may be found in the ‘Terms and Conditions of Service’ section, accepted by the client at the time of purchase.
Refunds can only be made for health emergencies, upon presentation of a self-declaration signed stating the emergency of the visitor.
