On this day we return to San Lorenzo (Saint Lawrence), one of seven pilgrimage churches of Rome, which were churches established for incoming pilgrims as "the" seven churches to visit on a pilgrimage. St. Laurence was a deacon of the church, an ally and associate to the pope, and was immensely popular in Rome. We have already visited the place of his martyrdom in the Church of San Lorenzo in Panisperna where the grill on which he was martyred is contained.
