Saint Peter’s is one of the 31 sites throughout the Archdiocese that has a designated and blessed door which when entered a plenary indulgence (removing all the punishment due to sin) can be gained by going through that door and fulfilling the means to obtaining an indulgence; that is, being in the state of grace before entering the door, make a sacramental Confession, receive the Eucharist at Mass, make a profession of faith and offer prayers for the Holy Father.  The indulgence can also be obtained for the deceased.  More info at
