The work has been designed as a travel reportage, across the Tuscan stages of the Via Francigena, from Pontremoli to Radicofani. The Via Francigena is the common name of an ancient road and pilgrim route running from France to Rome, though it is usually considered to have its starting point much further away, in the English cathedral city of Canterbury. As such, the route passes through England, France, Switzerland and Italy. The route was known in Italy as the "Via Francigena" ["the road that comes from France"]. In mediaeval times it was an important road and pilgrimage route for those wishing to visit the Holy See and the tombs of the apostles Peter and Paul.
