Passetto del Biscione

Tourists exploring nearby Campo de Fiori are often completely unaware of the existence of a hidden passageway connecting the Piazza del Biscione with via di Grottapinta.

Passetto del Biscione is tiny alley with a remarkable story. It was most likely named most likely after the eel, the heraldic symbol of the Orsini family who built their palace over the ruins of the Theatre of Pompey, Rome’s first theater. If you look carefully, you can trace the theater’s shape by observing the sequence of the buildings on the road.
