Sanctuary of San Callisto (Calepodio): Faith, History, and Adventure in Underground Rome
Nestled in the heart of Rome, the Sanctuary of San Callisto (Calepodio) is a place steeped in history, faith, and mystery. Located near the Catacombs of Callixtus, one of the largest and most important burial sites of ancient Rome, this sanctuary preserves the memories of the martyrdom of San Callisto and offers a unique experience for pilgrims and history enthusiasts.

An Ancient Place of Worship: From Catacombs to Sanctuary
The origins of the sanctuary are closely tied to the figure of San Callisto, a pope and martyr of the 3rd century. Tradition holds that Callixtus was martyred during the persecution under Aurelian and buried in the Calepodio cemetery, situated along the Via Aurelia. This underground cemetery, spanning over 20 hectares, became an important burial site for Roman Christians and, later, a center of veneration for San Callisto.
From the mid-4th century onward, the area around San Callisto’s tomb underwent significant transformations. The space was expanded and lined with masonry, while the tomb was converted into an arcosolium, adorned with marble slabs and a masonry altar. These modifications reflect the growing importance of the site as a pilgrimage destination.
During the 6th century, a new staircase was built to facilitate pilgrim access, and an apse was added to one of the walls, further enriching the sanctuary’s architecture.
San Callisto and Sant’Asterio: Heroes of Faith and Courage
The history of the Sanctuary of San Callisto is inextricably linked to two emblematic figures: San Callisto and Sant’Asterio. San Callisto, pope from 217 to 222, was a zealous pastor and defender of the faith, known for his charity and care for the poor. His martyrdom made him a symbol of courage and Christian witness.
Sant’Asterio, a Roman presbyter, is venerated for retrieving the body of San Callisto after his martyrdom and giving it an honorable burial in the Calepodio cemetery. His act of piety and respect for the martyr reflects the deep faith and devotion of early Christians.
Traces of a Glorious Past: Art and Archaeology in the Sanctuary
The Sanctuary of San Callisto preserves precious remnants of its glorious past. Fragments of a fresco depicting an episode from San Callisto’s martyrdom are still visible in the sanctuary, offering a moving glimpse into the saint’s life and death.
An inscription carved on a marble shelf, bearing the phrase “Alfius votum solvit” (“Alfius fulfilled his vow”), attests to the devotion of pilgrims who visited the sanctuary, offering gifts and prayers in gratitude.
The interventions of Pope Gregory III (731–741), who promoted restoration and embellishment works in the sanctuary, enriched its artistic heritage with painted decorations that some scholars date back to that period.
