Today the King and Queen celebrated their golden wedding anniversary. Although the history of the Norwegian monarchy stretches back more than 1100 years, King Harald and Queen Sonja are actually the first king and queen to reach this milestone (King Oscar II and Queen Sophie were married for 50 years and six months, but were deposed a day after their 48th wedding anniversary). This afternoon the King and Queen drove to the Cathedral of Oslo in the same open-top Lincoln limousine which took them there fifty years ago to attend a service of thanksgiving. The Crown Prince and Crown Princess, Princess Ingrid Alexandra, Prince Sverre Magnus, Princess Märtha Louise and her daughters Maud, Emma and Leah Behn and Princess Astrid were also in attendance. Back at the Royal Palace afterwards, the King and Queen made an unannounced balcony appearance with their children, daughter-in-law and grandchildren.
