Via San Gregorio Armeno is a street in the historic center of Naples, famous for its artisan workshops of nativity scenes. The street that is popularly called San Liguoro, is one of the stenoporos (from the Greek: stenosis, narrowing, and poros, passage) typical of Greek urban architecture which characterizes the entire ancient center of Naples. As a stenoporos (a cornerstone in Roman urban planning), the street served as a connection between the two plateia (from the Greek: plateia piazza) the larger plateia (current Via dei Tribunali) and the lower one (current Spaccanapoli). The two main streets of ancient Neapolis (from the Greek “New City”), today’s Naples, were therefore joined perpendicularly by this very street, at the height of the Basilica of San Lorenzo Maggiore, where the agora stood.
