For many centuries, Rome has been a destination for millions of tourists every year. What attracts them are the archaeological remains of the empire, the artistic wonders that have overlapped over the centuries, but also (and above all) its being the center of Christianity. During the episode, Alberto Angela takes a journey to the many places, monuments and buildings that have made the history of Christianity. The journey touches the main Basilicas but also more secluded, hidden corners of the city, where there are important testimonies of the history of the Church.

Le meraviglie della Roma cristiana includono basiliche iconiche come San Pietro e Santa Maria Maggiore, nonché il Colosseo, simbolo del martirio cristiano. Questa città eterna è intrisa di storia religiosa e offre una profonda connessione con il cristianesimo.
