On Monday Guillaume was on hand to celebrate the centenary of Lycée Robert Schuman. The festivities were held at the Philharmonie de Luxembourg.
Sadly, there was only one photo of this event. I looked around and couldn't find anything else. Oh Manuel Dias where have you been?
I think it's safe to say that Guillaume is officially working as Hereditary Grand Duke on a full time basis now. The number of events and engagements he undertakes has increased dramatically since he graduated from Angers. Guillaume appears more active than anyone else in the family. I understand, of course, that the Grand Duke has many responsibilities outside of public engagements.
