All three children of Prince William and Catherine, Princess of Wales, were in attendance for the coronation of their grandfather, King Charles III.

While Princess Charlotte, 8, and Prince Louis, 5, stuck close by their parents, who are next in line for the throne after Charles, Prince George has his own special role as a page of honor.
