The Decumano or Decumanus Superiore was one of the three main east-west roads (Decumani) in the Ancient Roman city of Naples.
This street is the upper (superiore) and most Northern of the three decumani, or east-west streets, of the grid of the original Greco-Roman city of Neapolis. The central main Decumanus Maggiore is now Via dei Tribunali; while the southernmost or lower Decumanus Inferiore is now Spaccanapoli. The three decumani were (and still are) intersected by numerous north-south cross-streets called cardini, together forming the grid of the ancient city.
