Certain saints' bodies were found in unusual states of preservation after burial. This page surveys major cases, how Catholic sources describe them, and what kinds of records survive.
No EmbalmingDecades to Centuries of Preservation
Nevers remains one of the central living pilgrimage sites in modern Catholic discussion of incorruptibility.Official sanctuary image
Public record type
Exhumation reports and shrine records
Most incorruptibility files survive through diocesan documentation, sanctuary pages, and later survey works rather than modern lab studies.
Typical evidential question
Preservation beyond burial conditions
The central issue is whether the documented state of the body fits the climate, coffin, and elapsed time recorded in the file.
Modern access limit
Custodial control by shrines
Most relic shrines do not permit new destructive scientific sampling, so later researchers often work from older exhumation records.

These shrines preserve some of the best-known current public records in the category.
Incorruptibility — in Catholic tradition — refers to the anomalous preservation of a saint’s body after death, lasting far beyond what would normally be expected given the circumstances of burial, climate, and time elapsed.[1]
It is not the same as:
Mummification — a natural process requiring specific dry, arid conditions
Embalming — which Catholic canonization practice has historically prohibited or discouraged for sainthood candidates, precisely to prevent artificial preservation from confusing the issue[1]
Petrification or fossilization — geological processes that alter tissue into mineral form
In Catholic usage, incorruptibility refers to anomalous soft tissue preservation — skin, sometimes organs, sometimes even facial features — in bodies that should have fully decomposed, buried in conditions that do not favor natural preservation.[1]
First exhumation: 1909 (30 years after death) — body found intact; slight color changes to skin and some joints, but soft tissue and facial features preserved; slight smell of fresh earth
Second exhumation: 1919 (40 years after death) — body still intact; relics taken
Third exhumation: 1925 (46 years after death) — body still intact; face appeared discolored from previous washing, so a wax mask was made over the face; body enshrined
Current state: The body of St. Bernadette is enshrined at the Chapel of Saint Gildard, Nevers. The wax face and hands are a covering, as the sanctuary explains. The underlying body shows signs consistent with natural mummification: Dr. Comte’s 1919 report noted “practically mummified” conditions with patches of mildew and calcium salt deposits.[1][3]
Forensic notes: Drs. Comte and Larson, who examined the body at the second and third exhumations, noted that the preservation was not consistent with the damp burial conditions in the convent crypt.[3] The body had been buried in a damp wooden coffin in a limestone crypt — conditions that should have accelerated, not retarded, decomposition. However, natural mummification is not impossible even in suboptimal conditions; it occurs when a body desiccates past the putrefaction threshold before bacterial decomposition completes. No peer-reviewed forensic paper has examined her remains. The reports come from exhumation physicians whose notes are held by the Congregation of Notre Dame, not published in scientific journals.
Initial burial: Interred without a coffin, in the ground, in a common grave. After 18 days, other sisters reported a sweet scent emanating from the burial site, and her body was exhumed.[1]
Finding: The body was found perfectly preserved and emitting a sweet fragrance.[1]
Current state: St. Catherine has been seated in a gilded chair in the Chapel of the Poor Clares in Bologna since the 15th century — over 560 years. She is one of the oldest known incorrupt bodies in the Catholic tradition.[1]
Note: The initial burial without a coffin, in common ground, makes any natural preservation explanation particularly difficult. The 18-day timeline — before a coffin could create anaerobic conditions — is especially significant.
St. John Vianney was the parish priest of the small village of Ars, known for spending up to 18 hours per day in the confessional and for reportedly possessing the gifts of reading souls and prophecy. Tens of thousands traveled to Ars annually during his lifetime to make their confession.[1]
Exhumation: 1904 (45 years after death) — body found perfectly intact, with soft tissue, skin, and facial features preserved. The body was described by the examining commission as looking as if it had been preserved by art, though no embalming had been performed.[1]
Current state: The body of St. John Vianney is enshrined at the Basilica of Ars, France. The face and hands visible in the shrine are wax overlays; the preserved body is beneath.[1]
Died: September 27, 1660 (age 79) — Paris, France[1]
St. Vincent de Paul founded the Congregation of the Mission (Vincentians) and the Daughters of Charity, and is considered one of the great saints of the 17th century.[1]
Exhumation and preservation: His body was exhumed and found intact. The skeleton and some tissue have been preserved; the face visible in his shrine at the Motherhouse of the Daughters of Charity in Paris is a silver reliquary mask.[1]
Note: The remains of St. Vincent survived the French Revolution — a period of intense anti-Catholic violence and destruction — and the relics were hidden and then restored.[1]
Died: September 23, 1968 (age 81) — San Giovanni Rotondo, Italy[1]
Padre Pio (Francesco Forgione) bore the stigmata — wounds corresponding to the crucifixion wounds of Christ — for 50 years, from 1918 until his death.[1] The wounds were medically examined multiple times and found to defy normal healing patterns.
Exhumation: 2008 (40 years after death) — the body was found largely intact and is currently enshrined at the Sanctuary of Santa Maria delle Grazie in San Giovanni Rotondo.[1]
The most comprehensive survey of incorruptible saints in English remains The Incorruptibles by Joan Carroll Cruz (TAN Books, 1977).[1] Cruz documents over 100 cases with references to canonical investigation records, exhumation documentation, and medical testimony.
Cruz was a laywoman and researcher, not a theologian. Her approach was documentary rather than devotional. The cases she surveyed ranged from the 3rd century to the 20th, across dozens of countries and climates — making the phenomenon difficult to attribute to a specific cultural or geographic factor.[1]
In Catholic theology, the incorruption of saints’ bodies is not treated as a stand-alone demonstration by itself. Rather, it is understood as a sign consistent with the Catholic understanding of the resurrection of the body, which holds that the human body, not just the soul, is destined for eternal life.[4]
Catholic sources do not usually try to explain the mechanism of incorruptibility. They note the anomaly, document it, and place it within a wider religious framework.
## Best first pages in this section
If you are new to incorruptibility files, these are the clearest first entries depending on whether you want exhumation detail, shrine continuity, or a famous linked apparition story.
Start with the best-known modern shrine case
Open the file. Bernadette is the easiest first page because the exhumations, wax covering, and present shrine setting are all clearly documented in public.
Start with the Rue du Bac connection
Open the file. Catherine Labouré is the best opening if you want an incorruptibility file tied directly to a famous apparition and medal tradition.
Start with a long Paris shrine record
Open the file. Vincent de Paul works well if you want to begin with early modern exhumation memory and a body now shown in a major Paris reliquary setting.
Start with the long Paris reliquary file
Open the file. Vincent de Paul is a helpful companion to Catherine because it shows a different kind of Paris shrine continuity and body presentation record.
