Italy’s ancient landscape hides more than just ruins above ground—beneath the surface lies a shadowy world of underground burial chambers and forgotten passageways. These subterranean realms have witnessed the rise and fall of empires, sheltered persecuted groups, and preserved artistic treasures that might otherwise have been lost to time.
The silent corridors hold whispers of the past, from early Christian rituals to secretive pagan ceremonies. Here is a list of 20 remarkable Italian catacombs that continue to fascinate visitors with their historical significance and mysterious ambiance.
Catacombs of San Callisto
The Catacombs of San Callisto represent one of Rome’s largest and most significant burial networks, spanning nearly 12 miles of underground tunnels. These labyrinthine passages once housed the remains of 16 popes and dozens of Christian martyrs, earning them the nickname ‘Little Vatican’ among early followers.
The walls still bear ancient Christian symbols, including fish, anchors, and the Good Shepherd, carved when these believers needed to conceal their faith from Roman persecution.
Catacombs of San Sebastiano
Located on the ancient Appian Way, the Catacombs of San Sebastiano were among the first to be called ‘catacombs’—a term that eventually described all similar underground burial sites. The catacombs contain unique architectural elements, including three intact mausoleums and several well-preserved frescoes depicting biblical scenes.
What makes these catacombs particularly special is their graffiti wall, where ancient visitors carved prayers for Peter and Paul, providing concrete evidence that these apostles were venerated in Rome.

Catacombs of Domitilla
Stretching across more than 10 miles and containing roughly 150,000 burial sites, the Catacombs of Domitilla represent the largest burial network in Rome. The site features a rare underground basilica carved directly from the soft tufa rock, dedicated to martyrs Nereus and Achilleus.
Art historians prize the catacomb’s 4th-century fresco of Christ teaching the Apostles—one of the earliest depictions of Jesus as bearded rather than in the youthful Apollo-like style common in earlier Christian art.
Naples Catacombs of San Gennaro
Unlike Rome’s narrow and winding burial tunnels, Naples’ Catacombs of San Gennaro features unusually wide corridors and high ceilings—a cathedral-like atmosphere carved underground. The walls display remarkable Byzantine-influenced frescoes alongside 5th-century mosaics that shimmer mysteriously in the dim light.
The central baptismal font, carved from solid stone and featuring original plumbing, indicates that these spaces served living communities as well as the deceased.
Naples Catacombs of San Gaudioso
Hidden beneath the Basilica of Santa Maria della Sanità lie the Catacombs of San Gaudioso, named for an African bishop who was shipwrecked near Naples in the 5th century. These catacombs are notorious for their macabre burial practice known as ‘scolatoi’—a draining process where deceased nobles were seated in carved niches until decomposition was complete.
Artistically, the site contains some of southern Italy’s finest catacomb frescoes, including vivid scenes of saints and martyrs alongside more ordinary depictions of tradespeople with the tools of their crafts.

Catacombs of Santa Lucia
Syracuse’s Catacombs of Santa Lucia form part of an extensive underground network beneath Sicily’s ancient capital, rivaling Rome’s catacombs in size and complexity. Unlike many Italian catacombs, these passages include ingenious water management systems, suggesting they occasionally served as emergency shelters during the frequent raids that plagued coastal Sicily.
Recent archaeological work has discovered pre-Christian sections dating back to Greek colonization, making these catacombs a remarkable timeline of Sicilian religious history.
Catacombs of Villa Torlonia
The Jewish Catacombs of Villa Torlonia represent the only known extensive Jewish underground cemetery in Rome, offering crucial insights into ancient Jewish life in the imperial capital. The complex features over 60 burial chambers decorated with symbols distinctly different from Christian sites—menorahs, oil lamps, and the Ark of the Covenant appear instead of crosses and fish.
Many tombs still bear touching inscriptions praising the deceased for their knowledge of the Torah or their generosity to the poor—virtues valued in the community.
Monterozzi Etruscan Necropolis
While not technically catacombs in the traditional sense, the underground tomb network at Monterozzi in Tarquinia preserves Italy’s most important collection of pre-Roman Etruscan paintings. The vivid frescoes depict banquets, sporting events, hunting scenes, and musicians—suggesting the Etruscans viewed the afterlife as a continuation of earthly pleasures rather than a spiritual realm.
The artistic techniques used in these underground chambers influenced later Roman and even Renaissance painting styles, creating a direct line between Italy’s earliest civilizations and its artistic golden age.

Palermo Capuchin Catacombs
Perhaps Italy’s most unsettling underground site, the Capuchin Catacombs of Palermo, contains nearly 8,000 mummified bodies arranged in thematic corridors rather than hidden in burial niches. Families would visit their preserved relatives on special occasions, sometimes changing their clothes or positioning—treating them almost as if they were still participating in family events.
The most famous resident is Rosalia Lombardo, a two-year-old girl who died in 1920 and whose remarkably preserved body appears so lifelike visitors often mistake her for a sleeping child.
Catacombs of Priscilla
Known as the ‘Queen of the Catacombs,’ this complex contains some of the earliest Christian art in existence, including the world’s oldest known depiction of the Virgin Mary with a Child dating from the early 3rd century. A section called the ‘Greek Chapel’ contains elaborate biblical scenes, including a representation of the Eucharist that provides evidence of how early Christians performed this ritual.
Archaeologists have found an unusual number of women’s tombs bearing titles like ‘presbytera’ (female presbyter), suggesting women may have held leadership roles in the early Church—information later expunged from official histories.
Catacombs of St. Agnes
Built around the tomb of the young martyr Agnes, these catacombs feature unusually large burial chambers that could accommodate dozens of family members who wished to be interred near the saint. The catacombs contain distinct architectural innovations, including small windows between family chambers—possibly designed to allow shared oil lamps to illuminate multiple rooms or to create the sense that families remained connected even in death.
Visitors can still see the original silver and gold leaf details on some ceiling decorations, materials rarely found in other catacombs due to looting throughout the centuries.

Catacombs of Vigna Randanini
Another of Rome’s Jewish catacombs, Vigna Randanini, features distinctive seven-branched menorahs carved directly into the tufa walls alongside inscriptions in ancient Hebrew, Greek, and Latin. Unlike many Christian catacombs, these passages include decorative elements from classical Roman design—floral motifs, mythological figures, and architectural embellishments that would have been forbidden in more orthodox Jewish communities.
The catacombs also contain evidence of professional guilds within the Jewish community, with tombs grouped by trade and decorated with the tools of various crafts.
Catacombs of Commodilla
Tucked away in a lesser-visited area of Rome, the Catacombs of Commodilla contains some of the best-preserved 6th to 9th-century frescoes, representing the transition from late Roman to medieval artistic styles. The site features a remarkable portrait of Christ with surprisingly Asian features—possibly the work of an artist from the Eastern provinces of the Byzantine Empire who brought different iconographic traditions to Rome.
The catacombs also contain rare examples of inscriptions written in Latin using Greek letters, a practice that demonstrates the cultural fusion occurring during late antiquity.
Chiusi Catacombs of Santa Mustiola
Located in Tuscany, the Catacombs of Santa Mustiola represent one of the few significant Christian burial networks outside of major cities, indicating how widely the religion had spread by the 4th century. The complex contains unusual family tombs designed with small openings through which liquid offerings could be poured on specific commemoration days—a practice that combined pagan ancestor worship with Christian prayers for the dead.
Distinctive local pottery found in burial niches displays a fascinating blend of Etruscan decorative traditions with Christian symbols, illustrating how regional cultures shaped religious expression even within standardized Christian practices.

Catacombs of Saint Lucy in Syracuse
Not to be confused with Naples’ Santa Lucia catacombs, this Sicilian complex was carved from the same stone quarries that provided building materials for ancient Syracuse, creating unusually high ceilings and wide passages. Archaeological evidence suggests the site was repurposed multiple times—serving variously as a pagan burial ground, Christian cemetery, Muslim storage facility during Arab rule, and Norman defensive position.
One chamber contains a remarkable Byzantine painting known as the ‘Madonna of the Catacombs,’ which survived the 8th-century iconoclasm that destroyed similar images throughout the Eastern Empire.
Catacombs of St. Paul in Rabat, Malta
While geographically part of Malta rather than mainland Italy, these catacombs were created during Roman rule and share the same cultural and religious context as Italian sites. The underground network features distinctive agape tables—circular stone dining platforms where memorial meals were shared by families commemorating their deceased relatives.
The catacombs contain separate sections for pagans, Jews, and Christians, sometimes with connecting passages between them, suggesting these communities maintained contact despite religious differences.
Catacombs of San Giovanni in Syracuse
These extensive Sicilian catacombs feature a main tunnel nearly 130 feet long and 10 feet wide—dimensions resembling an underground basilica rather than typical catacomb passages. The burial chambers contain distinctive water wells that serve both practical and symbolic purposes—providing actual water for visitors while representing the Christian concept of living water and eternal life.
The catacombs contain several inscriptions in Greek rather than Latin, reflecting the strong Hellenic influence that persisted in eastern Sicily even during Roman rule.

Catacombs of Porta d’Ossuna in Palermo
Discovered accidentally during construction work in the 18th century, these pre-Christian catacombs reveal how burial practices evolved in Sicily from the Phoenician period through Roman times. The catacombs contain stone benches arranged in semicircles where families would gather for funeral banquets—a practice documented in both pagan and early Christian traditions throughout the Mediterranean.
Archaeologists have recovered distinctive oil lamps with both pagan and Jewish symbols, suggesting the site served a diverse urban population during Palermo’s golden age as a trading hub.
Roman Hypogeum of Via Livenza
This small but significant underground complex represents a rare example of a private pagan burial chamber that was later adopted by Christian users. The hypogeum features an unusual ventilation system with terracotta pipes that brought fresh air to the underground chambers, allowing mourners to burn incense and spend longer periods underground without discomfort.
The complex includes a unique double tomb designed for a married couple, with carved portraits showing them holding hands—a touching personal detail rarely preserved in ancient burial contexts.
Mithraic Catacombs of San Clemente
Hidden beneath the medieval Basilica of San Clemente lie chambers that once housed a temple to Mithras, a Persian deity popular among Roman soldiers whose secretive all-male cult rivaled early Christianity. The site demonstrates how underground spaces in Rome were repurposed over centuries, with this location serving variously as a noble’s home, Mithraic temple, Christian worship space, and finally, the foundation for the current church.
The chambers maintain their original water features, including a spring that continues to flow today—a natural phenomenon that likely contributed to the site’s selection for religious purposes.

Hidden Heritage Beneath the Surface
Italy’s underground burial networks represent more than just macabre tourist attractions—they form crucial historical archives where art, architecture, and inscriptions survived when similar examples above ground were destroyed by time, conflict, or zealous reformers. These subterranean spaces tell stories of religious persecution, cultural transformation, and personal devotion that official historical records often overlooked or deliberately obscured.
As modern archaeological techniques continue to develop, these silent corridors will undoubtedly yield more secrets about the lives, deaths, and beliefs of those who created Italy’s extraordinary cultural legacy.
