Each of the four papal basilicas in Rome has one Holy Door, normally sealed from the inside with masonry; the Pope opens St. Peter's at the start of a jubilee and the other three follow within days. In 2025 a fifth door was opened at Rebibbia prison, closed on December 21, 2025. Between jubilees you can see the doors from outside and, at St. Peter's, the bronze door panels from the portico, but you cannot pass through them.
Ordinary jubilees fall every 25 years, so 2050 is next on the fixed calendar. Pope Leo XIV said in November 2025 that Christians should walk toward a Jubilee of the Redemption in 2033, two thousand years after the Passion, with Jerusalem at its center, and in June 2026 asked all Christian denominations to mark it together; whether Rome will open Holy Doors for it has not been announced. Extraordinary jubilees can also be called at short notice, as in 2015 for the Year of Mercy.
Passing through a Holy Door was one of the ways to gain the Jubilee indulgence, not a sacrament in itself; the ordinary plenary indulgence remains available on pilgrimage to the papal basilicas at any time. The nature of the door is explained on what-is-a-holy-door-and-when-can-pilgrims-enter, and the 2033 announcement on what-has-been-announced-about-a-jubilee-of-the-redemption-in-2033.
