Pope Francis is bringing his Holy Year to Rome’s main prison. Francis traveled to Rebibbia prison on a frigid morning.

Pope Francis made a visit on Thursday to one of the largest prison complexes in Italy, opening a special "Holy Door" for the 2025 Catholic Holy Year, in what the Vatican said was the first such action by a Catholic pontiff.

Amid security worries, millions of pilgrims are expected to descend on Rome for a Jubilee Year of major Catholic celebrations throughout 2025. Here are the highlights.

Pope Francis urged inmates to never give up hope as he inaugurated the Vatican’s Jubilee Year at the high-security Rebibbia prison on the outskirts of Rome on Thursday.

Opening the Holy Doors of St. Peter’s Basilica on Christmas Eve, Pope Francis inaugurates a jubilee year expected to draw 32 million visitors to Rome.

As the Pope left the Rebibbia prison, he stopped to greet the 300 inmates and staff who had waited outside of the crowded chapel on the cold December morning.

"I wanted all of us, inside or out, to have an opportunity to throw open the doors of our hearts and understand that hope does not disappoint."

At the start of Christmas Eve Mass, Francis pushes open the great Holy Door at the entrance of St. Peter’s Basilica.

Pope Francis kicked off the Jubilee this week, marking the start of the Holy Year in Italy as 32 million pilgrims are expected to travel to Rome this year.
