On Monday, Queen Sonja and Crown Princess Mette-Marit attended the unveiling of Louise Bourgeois' Monumental Sculpture "Maman" in the Palace Park.

In her speech, Queen Sonja said: “On her thin but strong legs, Louise Bourgeois' Maman has crawled and spun her way through the world - from New York in the west to Tokyo in the east, from Bilbao in the south and here to the springtime Palace Park in Oslo, surrounded by living congeners.”

Queen Sonja wore an Æ Rainwear poncho with black trousers.

Crown Princess Mette-Marit wore a Fleischer Couture poncho with navy trousers and her Ganni boots.
