We recommend that you book your visit online in advance to be sure of your place. As long as capacity permits, you can also buy tickets at the box office.
Do you have an UiTPAS, ICOMkaart, HHG jaarkaart or voucher? Then you can also book online. Show your pass on the spot that entitles you to reduced or free admission.
There is no need to book online in advance if you are a CityCard holder.
