Meet your guide and start the 50-minute drive outside of Rome to the tombs underneath Civitavecchia. Visit the Catacombs of San Sebastiano, the oldest Christian cemetery in Rome. Walk through the miles of underground passageways that make up this sacred site. Stand in the cavernous underground chambers where early Christians congregated. Hear about the burial practices of early Christians, and see religious symbols carved into the walls. Next, visit the Catacombs of San Callisto, the largest and most significant early Christian burial site in Rome. Travel back in time to the 2nd century and see the resting place of 10 martyrs, 16 popes, and hundreds of early Christians who died for their faith. Learn about the persecution of Christianity under the Romans as you walk through the underground labyrinth. Contemplate the faith of early believers in Christianity as you make your way through this somber resting place. Afterward, relax in the beautiful garden outside before returning to the port of Civitavecchia.
