Saint Petronille Chapel
The remains of Saint Petronilla were removed from the Via Ardentina in 757 and brought to a mausoleum near St. Peter’s. This building was renovated and became the Chapel of St. Petronilla. The chapel was used as the burial site for French kings.
The reason Saint Petronille is associated with the French kings is because Charlemagne and Carloman were the adopted sons of Saint Peter. Saint Petronille became the patron saint of the French kings.
The Feast of Saint Petronille
The feast of Saint Petronille is celebrated on May 31. Mass is celebrated at St. Peter’s cathedral on this day and is offered for the intentions of France. Many French people living in Rome attend the Mass in honor of Saint Petronille.
Many Catholics, especially French Catholics wear a Saint Petronille medal or a Saint Petronille pendant on her feast day. They pray to this early Christian martyr for strength in answering the call of Jesus.
