Welcome to this site which has been specially designed for you.
I am Guillaume, the new Grand Duke. I succeeded my father, Henri, on 3 October. And to celebrate this event, the website was updated.

You’ll find the answers to the questions you’ve been asking yourself: What is an abdication and a change of throne? What is the role of the Head of State? Why is there a Grand Duke and not a King? And loads more!

You'll also get to meet the Grand Duchess and our whole family. At the end, there's a short quiz to test what you've learnt during your visit!

Enjoy the visit!
