Denmark's King Frederik X and Queen Mary travelled to Oslo for a state visit on Tuesday and also spent their wedding anniversary there.
The two said "I do" 20 years ago in the Church of Our Lady in Copenhagen.
On their first official trip to Norway as king and queen of Denmark, they visited Norway's 87-year-old King Harald V and his wife Queen Sonja.
They were also received by Crown Prince Haakon and Crown Princess Mette-Marit of Norway.
The state visits to Norway and last week to Sweden followed Frederik taking the throne in January after his mother, Queen Margrethe II, unexpectedly abdicated.
