On May 1, several Catholic royals gathered in Vatican City for the beatification of Pope John Paul II. Beatification is a step toward making the former pope a saint and it means that he can now be called "Blessed John Paul" and Catholics can pray in his name. Among the royals attending the mass that day were King Albert II and Queen Paola of Belgium (pictured here), The Prince and Princess of the Asturias and the Grand Duke and Duchess of Luxembourg. Between the royal wedding in London, Queen's Day celebrations in The Netherlands, the King's birthday in Sweden and the Beatification, it was a very busy weekend for most of Europe's royals.
