The Passetto del Biscione: The Secret Passageway with the Miraculous Fresco

You might walk right past Campo de' Fiori, among the market stalls and the tourists queuing for gelato, without ever imagining that a few metres away a door opens onto another time. The Passetto del Biscione is exactly that: a short covered passage linking Via di Grotta Pinta with Piazza del Biscione, so discreet that most of the people walking through it never stop to look up.

And yet all it takes is to raise your eyes. The vault and the walls are covered with frescoes of cherubs, festoons and trompe-l'oeil architecture, brought back to light by a lengthy restoration promoted by the Centro Studi Cappella Orsini and completed around the mid-2010s. The light here is low, filtered, almost crypt-like: a few metres that completely change the rhythm of the walk.

The heart of the place is its little Madonna. Originally the passage held a famous sacred image painted by Scipione Pulzone, later moved to the church of San Carlo ai Catinari, where it still hangs. In its place another depiction of the Virgin remained, and it is to this one that the episode which made the Passetto famous is tied: in 1796 it is said that the Madonna moved her eyes, unleashing a sudden and intense outpouring of popular devotion.

There is also a linguistic detail that raises a smile. From this image, so well hidden, is said to have come the Roman saying "cercare Maria per Roma" (to search all of Rome for Maria), used to mean chasing after something almost impossible to find. The curved shape of the passage is no accident: it follows the ancient foundations of the Theatre of Pompey, the city's first permanent masonry theatre, of which this corner still preserves the underground memory.

Visiting it is simple and free: you walk in freely, allow yourself a few minutes of silence and come out the other side, back into the hum of the centre. Precisely because of its fragility it deserves respect: keep your voice down, no flash, no hands on the frescoes. It is an honest way of giving something back to a place that asks only to be noticed.

Getting there

The passageway lies in the heart of the historic centre, just a few steps from Campo de' Fiori: it is easily reached on foot from Corso Vittorio Emanuele II, Piazza Navona or Largo di Torre Argentina. By car it is best to leave the vehicle outside the ZTL, since the whole area is a restricted-traffic zone. Several bus lines stop nearby along Corso Vittorio Emanuele and Largo Argentina; the metro stations are farther off, while from Roma Termini you can easily reach it by surface bus. The nearest airport is Rome Fiumicino, with Ciampino as an alternative.
