If an attraction is closed on the day of your visit, you can find this information in the opening hours calendar on the website. By clicking on the date of your visit, you can see which attractions are closed that day. This may happen, for example, during scheduled maintenance or when an attraction needs to remain closed for several consecutive days.
In case of short-term or temporary closures, it is unfortunately not always possible to update the website in time. If an attraction is closed, this will also be communicated at the entrance of the attraction with a sign. Often, an estimated time when the attraction might reopen will also be indicated.
