As the nation enjoyed what was an historic occasion full of traditional British pomp and ceremony, the children of William and Catherine, the Prince and Princess of Wales, threatened to out-shine the King’s big day.
With George playing his role of Page of Honour splendidly, his little brother and sister sat with their parents in the front row taking in all of the action.
Here are 20 images from what has been a stunning display of pageantry.
