Journey is probably the first key word to understand this Visitor Center. An authentic journey, with thousands of questions on the things we see, the places we go through, the environments surrounding us. This is the reason why we will find at the entrance of the Center a "Question Machine" introducing the visit and making us understand that curiosity, with the thousands of questions we ask to ourselves and the others, is not at all a lack, but is the engine of knowledge, the reason of a real journey.
