 The three "decumani" were (and still are) intersected by numerous north-south cross-streets called "cardini", together forming the grid of the ancient city.Today, the street officially starts at Piazza Gesù Nuovo and is officially named "Via Benedetto Croce".Moving east, the street changes name to "Via S. Biagio dei Librai" and then crosses "Via Duomo" (named for the Cathedral of Naples) and moves beyond the confines of the old center of town.
