Arnolfo di Cambio
Since Pope John Paul II's apostolic visit to the basilica in 1981, a medallion bearing the Papal arms has been placed beneath the cross on the northwest end. The red galero hats of Cardinals Rufino Santos and Jaime Sin are also suspended from the ceiling of the dome. In addition, a copy of Saint Peter's statue (attributed to Arnolfo di Cambio) is enshrined inside, across a polychrome life-sized statue of the Immaculate Conception.
