The royal couple and their four children were present at the traditional Te Deum mass at the Saints Michel et Gudule cathedral in Brussels.

Eeven though the king & queen have refused an annual dotation for their heir for the time being, Elisabeth's unofficial training has clearly taken a start with Belgian and international activities, when she's away from school.

Prince Gabriel (nearly 16) who's by now the tallest member of the royal family, had his foot in a (black) plaster because of a sports injury.
By 18:30 queen Mathilde had changed into another dress to visit the laidback party activities at the Parc de Bruxelles.
At 23:00 the royal family took their first row seats for the fireworks that concluded the festivities. For the first time all four children accompanied them.
The duchess of Brabant had changed into an airy Zimmermann dress.
