Archaeologists have dubbed the discovery the “Tomb of Cerberus” after the three-headed guardian dog.
The sealed burial site was found in Giugliano in Campania, about 12 kilometers north of Naples. The team was surveying the area ahead of planned water-supply expansion work.
The burial chamber, designed for multiple individuals, has remained exceptionally well preserved despite being more than 2,000 years old. The tomb was adorned with numerous frescoes that researchers described as “pristine.”

The fresco of Cerberus depicts the 12th and most dangerous labor of Hercules: his descent into Hades with Mercury to capture the three-headed dog.
Other mythological figures on the walls and ceiling include ichthyocentaurs holding shields. Nearby, Cupid appears with tiny wings.
The Discovery Site Revealed Ancient Construction Techniques
Previously, archaeologists had uncovered several ancient Roman burials in this area, as reported by the Daily Mail. During the current research, experts noticed a wall built using an ancient Roman construction technique known as opus incertum. This technique, called opus incertum, used square-shaped stones set in concrete. A heavy slab of volcanic ash and other deposits sealed the tomb’s entrance; archaeologists carefully removed it.

Mariano Nuzzo, head of the archaeology, fine arts and landscape department of the Province of Naples, said, “We uncovered frescoes on the ceilings and walls in perfect condition, depicting mythological scenes throughout the room.”
He added that researchers were particularly struck by “an altar with vessels for libations and elaborately decorated burial beds, where the deceased still rest.” Excavation work at the tomb is ongoing.
