The Francigena route was an important medieval pilgrimage path that stretched over 1600 km from Canterbury, England to Rome, Italy. Pilgrims would follow sections of old Roman roads to destinations like Aosta, Ivrea, Pavia, and Lucca before reaching Rome to visit St. Peter's tomb. In the 1970s, interest revived in restoring markings along the original route to support religious pilgrims and tourists wishing to experience the journey on foot.
