Yesterday evening, The Hereditary Grand Duke was in Amsterdam at the Royal Concert Gebouw to attend a gala concert given in honor of Princess Maxima's 40th birthday.
The 1,900 attendees included several hundred invited guests and paying members of the public. The conductor Mariss Jansons led the renowned orchestra through Rossini, Liszt and Von Weber.
Unfortunately, there are not many photos of Guillaume. Even real life princes are no match for the public's fascination with royal women. Luckily, Guillaume arrived behind Crown Princess Mary. If you are interested in seeing our dashing Hereditary Grand Duke, you will find him behind Mary and Frederick in most of the photos and directly behind Princess Maxima in the group photo. Guillaume is also photographed with his cousin Princess Maria Carolina de Bourbon de Parme.
You will find the photos at Isopix, Belga, Belga, Parool, Royalty, AT5, AT5, Royal Press Europe, and Maxima Fan. RTL has two videos of the concert including some of Princess Maxima's moving speech. Video 1, Video 2.
