We offer free admission to people with disabilities upon presentation of a letter from your organization specifying the number of people with disabilities, as well as the number of accompanying persons and their names, along with a valid MDPH certificate or notification. Otherwise, the full or reduced rate will apply. We offer a reduced rate of €14 per person for accompanying persons. Payment can be made directly on site in cash, by credit card, or by check, and it is not necessary to book your visit in advance.
