On Tuesday, Princess Marie attended an event celebrating the Kattegat Centre's 30th anniversary, as Patron. She was joined by Prince Joachim, Count Henrik, and Countess Athena.

In her speech, Princess Marie said: "Congratulations on 30 years in the service of the sea, where you have made more than 7 million guests more knowledgeable about life in the sea - or as you call it, smitten by the sea. You have done this by creating fantastic experiences based on nature below sea level. And the sharks circling below me, and all your other over 200 species of sea creatures, are all important ambassadors for their fellow species in the wild and are the source of your fascinating communication that has an important purpose: To make us all take better care of the nature of the sea.”

Princess Marie and her family then visited the new penguin facility where they fed the Kattegat Centre's 22 penguins.

They also visited the new school laboratory where they helped dissect a 10-armed octopus which was then fed by Princess Marie and her children to the tropical sharks in the shark tank.

Princess Marie wore her Max Mara coat with a black turtleneck, her Maje trousers, her Maje ankle boots, and her Rolex watch.

Count Henrik wore a Bombers Original jacket with a green jumper, burgundy rousers, and Nike sneakers.

Countess Athena wore an Uniqlo parka with a pink jumper, Zara trousers, and Converse sneakers.
