Thousands flooded through the walls of Vatican City as a procession of cardinals and pallbearers took the body of the late pontiff into St. Peter's Basilica.

Vatican authorities kept St. Peter's Basilica open all night as an estimated 50,000 people lined around St. Peter's Square and out of the Vatican into Rome to view the body of Pope Francis lying in state.

So many mourners lined up to pay their respects to Pope Francis that the Vatican kept St. Peter's Basilica open all night to accommodate them.
