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 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 Doors praying that the Holy Spirit would soften hearts so that "enemies may speak to each other again."
