The ancient Flaminia Street, diverticulum ab-Helvillo Anconam
It started on the right in Street Flaminia Roman bridge over the ditch Rigo and walked up the valley of the Fosso, Alceto or valley, on the side overlooking the left bank, reaching the slopes of Monte della Rocca, the plain between the Apennine boundary ditch and Fabriano. At the entrance of Valle Alceto began what could be called the right branch of the diverticulum (more or less coinciding with the existing road crossing).
