The route recalls the origins of Christianity and its first contact with the great powers of the ancient world. Along the way, visitors uncover legends used to instruct and inspire the faithful, such as the Bocca della Verità. The tour then enters the Jewish Ghetto of Rome to explore the lesser-known consequences of Christianization, walking through streets that preserve both pain and resilience. The journey concludes in Campo de’ Fiori, where history, faith, and human nature converge — a powerful ending to a walk through the complex legacy of the Church in Rome.
