Pilgrims and tourists are streaming into Vatican City ahead of Sunday’s historic event: the double canonization of John XXIII and John Paul II.

Italy's interior minister says as many as 1 million people could be drawn to Rome for the extraordinary occurrence of two pontiffs being canonized at a Mass on Sunday where two living popes will be present. The Vatican has confirmed that retired Benedict XVI will help Pope Francis and dozens of cardinals celebrate the Mass outside St. Peter's Basilica.

The square will open to the faithful Sunday morning before dawn, and many people had spread out sleeping bags and mats in the area just outside the Vatican in hopes of securing prime viewing spots. The sound of hymns being sung in Italian, Polish, English and other languages could be heard Saturday in much of Rome as pilgrims made their way through the capital heading from buses and trains toward the Vatican. Some pilgrims set out weeks ago from Poland to make the journey by foot; others were arriving by horseback.

Tens of thousands of faithful, many of them young people, will pack several churches throughout Rome late Saturday for a prayer vigil.
