Sanctuary of Saint Petronilla: A Journey through Faith, History, and Mystery

The Sanctuary of Saint Petronilla, once a focal point of devotion in papal Rome, now survives in historical documents and memories of a past rich in faith and art. This sacred place, dedicated to a Roman martyr venerated as the spiritual daughter of Saint Peter, holds a fascinating history that deserves to be rediscovered.

The History of the Sanctuary: From Origins to Demolition

The history of the Sanctuary of Saint Petronilla has its roots in the distant 8th century, when popes Stephen II (752-757) and Paul I (757-767) took important initiatives to honor the saint. Stephen II, in particular, promised King Pepin of the Franks to transfer the martyr’s body to the Vatican and had a basilica built iuxta basilicam beati Petri Apostoli … in loco qui Mosileos appellatur basilicam in honorem sanctae Petronillae (as reported in the Liber Pontificalis). This basilica became the first nucleus of a sanctuary that would attract pilgrims and devotees for centuries.

Renaissance drawings, preserved at the Uffizi (A 4336) and in the plan by Tiberio Alfarano, offer us a precious testimony of the original structure of the building: a mausoleum with a central plan, covered by a dome, with rectangular niches along the internal perimeter. In 1471, King Louis XI of France promoted restorations, the extent of which, however, remains unknown.

The Cult of Saint Petronilla and the Discovery of the Relics

The heart of the cult was the relics of Saint Petronilla, transferred from the Catacomb of Domitilla during the pontificate of Stephen II. In 1474, during some works, a sarcophagus with the inscription “AVR. PETRONILLAE FIL. DVLCISSIMAE” (Aurelia Petronilla, sweetest daughter) was discovered under the altar. The inscription was interpreted as confirmation that the remains of the saint martyr rested there, further intensifying veneration. These relics consisted of the saint’s bones.

Saint Petronilla is traditionally considered the spiritual daughter of Saint Peter. According to some hagiographies, Peter healed her from paralysis, and the saint refused marriage to a Roman nobleman to consecrate herself to God. Her figure thus embodies purity, unwavering faith, and devotion to Saint Peter, elements that contributed to her popularity in the Middle Ages and Renaissance.

The Legacy of the Sanctuary: Between History and Memory

Unfortunately, the history of the Sanctuary of Saint Petronilla had a premature end. In the first decades of the 16th century, the building was demolished. Despite its physical disappearance, the sanctuary continues to live in historical sources and religious iconography. Its memory is preserved in the Vatican archives, libraries, and museums, where documents and works of art testifying to its importance can still be admired.

Ideas for an Adventurous (and Virtual) Research

Even though the sanctuary no longer exists, its history offers several ideas for fascinating research:

• Vatican Archives: Deepening research in the Vatican archives might reveal new documents and information about the construction, management, and life of the sanctuary.
• Roman Libraries: Exploring Roman libraries, such as the Vatican Apostolic Library and the National Central Library of Rome, in search of manuscripts, drawings, and engravings depicting the sanctuary.
• Works of Art: Tracing and studying works of art (paintings, sculptures, frescoes) dedicated to Saint Petronilla and preserved in museums and churches in Rome.
• The Path of the Relics: Reconstructing, as much as possible, the path of Saint Petronilla’s relics after the demolition of the sanctuary.
• Virtual Reconstructions: Creating (or supporting) virtual reconstructions of the sanctuary based on Renaissance drawings and historical sources, to offer an immersive visualization of this lost sacred place.

Even though we can no longer physically visit the Sanctuary of Saint Petronilla, we can still undertake a virtual journey to discover its history, art, and spirituality. A journey that allows us to rediscover an important piece of Rome’s religious and cultural heritage.
