You are advised to buy tickets online as much in advance as possible. We have a limited number of entrance points to guarantee visitor comfort during the visit and some types of tickets or sessions fill up very quickly.
Above all, if you book one of our Guided Tours, it is important to book in good time if you want to guarantee your place, as they sell out quickly!
If you are a large group or a school, you certainly have to buy in advance. It is also very easy, just go here.
