Visit to the Seven Churches and the Seven Privileged Altars

Most ancient also is the custom of visiting in these Churches, but especially in St Peter on the Vatican, the seven privileged Altars. The seven Altars in St Peters are:

1.The Altar of Our Lady, commonly called the " Gregoriana";

2.Of SS. Processus and Martinianus;

3.Of St Michael the Archangel;

4.Of St Petronilla, Virgin;

5.Of Our Lady, commonly called "of the Pillar";

6.Of the Holy Apostles SS. Simon and Jude;

7.Of St Gregory the Great. Any of the faithful who shall visit devoutly these seven Altars may obtain the numerous Indulgences granted to these seven Altars by successive Pontiffs. The same Indulgences may be gained outside Rome in churches to which the privileges of the Seven Churches or the Seven Altars have been extended.
