Andrea Pozzo's trompe-l'oeil ceiling is one of the most astonishing optical illusions ever painted — stand on the marble disc in the nave to see it resolve into three dimensions. Free, no queue, 5 min from the Pantheon. Open Mon–Sat 7:30–19:00
Three Caravaggio paintings in the Contarelli Chapel — The Calling of Saint Matthew, in real light, is one of the most important paintings in the world. No ticket, no queue, just walk in and turn left. Open daily, closes for 2 hrs at midday
Bernini's Ecstasy of Saint Teresa — arguably the most erotic sculpture in any church in the world, lit from a hidden window above, in a private chapel on the left. Near Termini, almost no tourists. Free. Open 7:00–12:00 & 15:30–19:00
Bernini called this his only perfect work — an oval church so precisely designed that every element pulls the eye toward the altar. Free guided visits by the Jesuits. Closed Monday. Open Tue–Sun 8:30–12:00 & 16:30–18:00. Steps from San Carlo
Borromini's response to Bernini across the street — a tiny church crammed with mathematical complexity, the entire floor plan fits inside one of St. Peter's pillars. Free. Open Mon–Fri 10:00–13:00 & 15:00–19:00, Sat 10:00–13:00
Rome's only Gothic church, built on top of a temple to Minerva — Michelangelo's Christ the Redeemer stands inside, Fra Angelico is buried in the sacristy, and Galileo was forced to recant here. Free, open 7:00–19:00 daily. Never crowded
The Chapel of San Zeno contains 9th-century Byzantine mosaics so dense with gold they seem to emit their own light — called the "Garden of Paradise" by medieval pilgrims. Free, near Santa Maria Maggiore. Open 10:00–12:00 & 16:00–18:00 only
