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."

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.
