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.

Pilgrims from around the world have been passing through the open Holy Door of St. Peter’s Basilica this week.

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.

The pope opened the Jubilee Holy Door praying that the Holy Spirit would soften hearts so that "enemies may speak to each other again."

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.

Pope Francis inaugurated his Holy Year at Rome’s main prison on Thursday, bringing a message of hope to inmates and involving them in the Catholic Church’s once every quarter-century celebration that is expected to bring about 32 million pilgrims to Rome.
