World Youth Day Fast Facts

Pope Francis arrives on the popemobile at Rio de Janeiro's iconic Copacabana beachfront on July 25, 2013, for his welcome to World Youth Day ceremonies. On the fourth day of his visit to Brazil and borne along by adoring crowds, Pope Francis waded into the country's ramshackle slums and onto the front line of its fierce national battle over poverty and corruption, before going to the much wealthier district of Copacabana for his welcome by the youth.
