A 14-day walk on the ancient pilgrim route through Tuscany and Lazio, from Pietrasanta on the Ligurian Coast to Viterbo near Rome.

The Via Francigena is an ancient pilgrim route to Rome, starting originally in Canterbury. Walking from the Ligurian Coast (Pietrasanta near Pisa) to Viterbo took me about 2 weeks.
