Rome is on a lot of people’s minds this year. That’s because 2025 is a Jubilee year, a Holy Year for Catholics that takes place every quarter of a century. Millions of Catholics from every corner of the planet will be making a pilgrimage to the Eternal City (and, of course, Vatican City) to show their devotion and piety.

One of the Jubilee traditions is to pilgrimage to each of Rome’s four papal basilicas—Saint Peter’s, Saint John Lateran, Saint Mary Major, and St. Paul Outside the Walls—each one a masterpiece of historical art and architecture. Of the four, the basilica that gets the least attention—because of its location on the periphery of Rome—is St. Paul Outside the Walls.
