Crowds gathered outside the Grand Ducal Palace to witness the historic occasion. The new Grand Duchess Stéphanie, dressed in a gown mirroring the light blue of the Luxembourg flag, accompanied her husband, along with their sons, Princes Charles and François.
Guillaume becomes Luxembourg’s seventh Grand Duke since the establishment of the modern monarchy in 1890.

The day concluded with an evening gala hosted by the new Grand Duke for attending dignitaries.
