Basilica of Saint Paul Outside the Walls
The Via Francigena was an ancient pilgrim route between England and Rome. It was customary to end the pilgrimage with a visit to the tombs of Sts Peter and Paul. In 1300 Pope Boniface VIII declared the first Holy Year, granting a special indulgence to those, who meeting the requisite conditions, visited St. Peter's Basilica and the Basilica of Saint Paul Outside the Walls. Over time the number of prescribed churches increased to seven.
