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 see Pope Francis lying in state in a simple wooden coffin inside St. Peter’s Basilica that the Vatican kept the doors open all night due to a higher-than-expected turnout.

Pope Francis's body was moved to St. Peter's Basilica on Wednesday to allow Catholic faithful to pay their final respects ahead of a funeral expected to bring U.S. President Donald Trump and dozens of other world leaders to Rome.
