On this underground tour of Rome you will descend beneath the surface to explore the labyrinth of catacombs, caves, and passageways that extends for kilometers under the city. You will meet the specialist guide in the Appian Way area - one of the oldest and most important Roman roads, built in 312 BC - where you will receive a complete safety briefing and be handed professional torches. Then the descent into the early Christian catacombs and the tuff caves will begin, following safe but little-known routes far from the mass tourist circuit.
The expert guide in Roman underground archaeology will tell you the stories of the first Christian communities buried in the catacombs between the 2nd and 5th centuries AD, will explain the religious symbols carved into the walls (the Ichthys fish, the anchor of hope, the good shepherd), will show you how the tuff and pozzolana caves were quarried using manual techniques passed down for centuries, and will take you to see authentic World War II evidence still visible in the Roman underground.
You will walk through narrow passageways carved into volcanic rock, monumental galleries several meters high, hypogean chambers decorated with original early Christian frescoes, and spaces that have not seen sunlight for nearly 2,000 years. You will discover how tuff lionato a local volcanic tuff and red pozzolana, extracted from these quarries, were used to build iconic Roman monuments such as the Colosseum, the Pantheon, and the Baths of Caracalla.
Historical and Archaeological Context
Christian Catacombs of Rome: The Roman catacombs are ancient underground cemeteries used primarily by Christian communities between the 2nd and 5th centuries AD during the persecutions. In Rome there are approximately 60 catacombs with over 150 km of underground galleries housing around 750,000 burials.
Tuff Caves: Lionato tuff and red pozzolana are volcanic rocks extracted from the Roman subsoil since Etruscan times. These underground quarries supplied the building materials for much of ancient Rome, including the Colosseum, the Pantheon, and the Aurelian Walls.
WWII Shelters: During World War II (1943-1944), thousands of Romans took refuge in the catacombs and abandoned caves during the Allied bombing of Rome. Many of these testimonies are still visible today, including writings, graffiti, and period objects.
