Piazza di Sant'Ignazio, Rome, Italy
Church of St. Ignatius of Loyola at Campus Martius
A grand Jesuit church in central Rome dedicated to the founder of the Society of Jesus, famous for Andrea Pozzo's painted ceiling that creates the illusion of a soaring dome.
You walk in expecting a church and get an optical trick. Andrea Pozzo, a Jesuit brother and self-taught genius, painted the flat ceiling of this church to look like it opens into heaven — columns, arches, clouds, saints, all of it rising impossibly upward. Stand on the small marble disk in the nave floor and the illusion is perfect. Step off it and the whole thing warps and collapses. He did the same thing over the crossing, painting a fake dome on a canvas stretched over a flat surface because the neighbors complained that a real dome would block their light. The church was built between 1626 and 1650 to honor Ignatius of Loyola, whose remains rest in a side chapel under a wildly ornate altar designed by Pozzo. Lapis lazuli columns, gilded angels, a silver statue of Ignatius — it is Baroque excess at full volume. But the rest of the church is surprisingly calm. The nave is wide and well-lit, and the side chapels have good paintings that most visitors walk past because everyone is staring at the ceiling. Come in the afternoon when the light hits the frescoes right.

What to See
Start at the marble disk in the center of the nave and look up. The ceiling fresco depicts the missionary work of the Jesuits spreading across four continents, with Ignatius receiving light from Christ and passing it outward. Walk slowly away from the disk and watch the painted architecture bend and distort — it is the best demonstration of Baroque illusion in Rome. Then find the second disk near the crossing and look up at the fake dome. Most people cannot tell it is flat until someone points it out. The Chapel of St. Ignatius on the left transept is overwhelming in its decoration — look for the large lapis lazuli columns and the original silver statue by Pierre Legros. The side chapels dedicated to Jesuit saints Luigi Gonzaga and John Berchmans contain their relics and are worth a quiet visit.
Pilgrim Notes
The church is on Piazza di Sant'Ignazio, one of the most charming small squares in Rome, about a five-minute walk from the Pantheon. It is open daily and free to enter. Lighting for the ceiling fresco is coin-operated — bring small change or you will be squinting. Mass is offered daily in Italian. The church can get busy with tour groups midmorning but clears out by early afternoon. It pairs well with a visit to the nearby Church of the Gesu, the mother church of the Jesuits, just a few blocks south.
