Go down, and go back in time. On the green Celio hill, we descend through San Clemente from a 12th-century apse of gold to a pagan temple of Mithras, where an ancient spring still roars. We step into a 13th-century chapel painted like a storybook, stand inside Rome's mysterious round church, and finish in Roman homes still bright with frescoes of gods and birds. Three layers of history, two underground worlds, one unforgettable morning with a private guide born and raised in Rome.

Meeting Point

San Clemente

- In front of the Basilica

10:10 AM

San Clemente

Our journey starts at a modest door on Via Labicana and goes down through 2,000 years. Upstairs, the 12th-century church shines with a golden apse where a vine grows out of the Cross and curls across the vault, full of birds, animals and tiny figures at work: paradise imagined as a garden. Downstairs, the earlier basilica of the 4th century keeps medieval frescoes of Saint Clement's miracles, and one scene where the characters' speech is written in early Italian, a rare and very funny glimpse of how people really talked. At the bottom, in the cool and the dark, we reach a sanctuary of Mithras, the Persian god loved by Roman soldiers, and hear a spring that has never stopped flowing.

11:00 AM

Santi Quattro Coronati

Up the slope stands an abbey that looks more like a castle, built to protect popes in troubled centuries. Inside, a tiny chapel painted in 1246 tells one of the great stories of the Middle Ages: Constantine, sick and desperate, is cured by Pope Sylvester and in gratitude bows before him, offering him his crown. These vivid frescoes were a message to the emperors of the day about who held power in Rome. If the nuns have opened it, we also visit the medieval cloister, one of the most serene spots in the city.

11:30 AM

Santo Stefano Rotondo

Among the trees of the Celio rises a church unlike any other in Rome: perfectly round, ringed by ancient columns, built in the late 5th century as an echo of the Holy Sepulchre in Jerusalem. Its quiet light and vast circular space feel almost mystical. Then we look at the walls: a 16th-century cycle of martyrdom scenes, painted to move the faithful and famously disturbing to 19th-century travellers like Dickens, and a 7th-century mosaic with a jewelled cross.

12:10 PM

Case Romane del Celio

We walk down the Clivo di Scauro, a lane that has been a street since Roman times, crossed by medieval arches. Under the church of Santi Giovanni e Paolo we enter a hidden neighbourhood of Roman houses, shops and baths, used from the 2nd to the 4th century and then turned into a place of Christian worship linked to the martyrs John and Paul. The rooms still wear their colours: garlands, birds, painted figures, geometric panels, and a magnificent marine fresco where a goddess reclines among boats and cherubs.

Ending Point

in the peaceful square of Santi Giovanni e Paolo, a short walk from the Colosseum and Circus Maximus, with my suggestions for lunch and for the rest of your stay.

About Tour Guide Federico C.

Ciao! I'm Federico, a born-and-raised Roman with a passion for sharing the beauty, history, and authentic spirit of the Eternal City.


I've been welcoming travelers since 2016, and what I love most about my job is turning a visit to Rome into a truly memorable experience. For me, guiding is not just about showing monuments or explaining dates and facts — it's about bringing the city to life through fascinating stories, hidden corners, local traditions, and the little details that make Rome so unique.


From the grandeur of the Colosseum and the Roman Forum to the charming streets of Trastevere, I love helping visitors discover both the iconic landmarks and the lesser-known treasures that many travelers might otherwise miss.


But Rome is much more than its ancient history. It's also about delicious food, lively neighborhoods, beautiful viewpoints, local restaurants, and the vibrant atmosphere of everyday Roman life.


My approach is friendly, relaxed, and flexible. I believe every traveler is different, so I enjoy adapting each experience to your interests, pace, and curiosity — whether you're passionate about history and art, looking for authentic local experiences, exploring Rome with your family, or simply hoping to discover the city through the eyes of someone who calls it home.


I can share plenty of tips on where to eat, what to visit, and how to make the most of your time in Rome, including some of my favorite local spots.


My goal is simple: for you to leave Rome with a deeper understanding of its history, a taste of its lifestyle, wonderful memories, and perhaps the feeling that you've made a Roman friend along the way.


I look forward to exploring my beautiful city with you. Benvenuti a Roma!
