Full description
Enjoy a half-day walking tour of Christian Rome and discover underground treasures in some of the most sensational churches. Your guide will tell you fascinating facts along the way, leading you to the ancient Basilica of San Clemente, and the Cathedral of St. John in the Lateran Palace.

Start at the Basilica of San Clemente, the only church in Rome to be built on 3 different levels. Constructed from the 1st to the 12th centuries, 2 underground floors can now be explored, including the Altar of Mithras from the 1st century.

Continue to the church of the Santi Quattro Coronati, devoted to 4 anonymous saints and martyrs. In 2002, an extraordinary series of frescoes was uncovered depicting scenes from the Zodiac, Four Seasons, Liberal Arts, and King Solomon.

Follow the story of the Emperor Constantine and Pope Sylvester in the Chapel of St. Sylvester, where it is said the famous Constitutum Constantini (Donation of Constantine) took place.

End your tour at the Cathedral of Rome, also known as the Archbasilica of St. John Lateran. The oldest of the 4 Papal Basilicas, St. John Lateran boasts a splendid façade, but it’s the Scala Sancta (Holy Stairs) that will catch your eye.

Very interesting excursion

It was an unusual excursion, we saw things that are not usually visited, and we loved it. Great guide and very nice driver BUT I thought the driver would wait for us not to have to walk. He left us at the beginning of the tour and picked us up at the end and between the different basilicas we had to walk at 36 ° C and I thought we had hired a driver's tour.

Roberto Mercuri was the best guide we had in Italy - a must do tour!

Very informative, complete, personalized and enjoyable! Roberto's knowledge is extensive and his passion for the topics covered was evident throughout. It was also refreshing to have a guide who simply shared the information without feeling the need to inject a "self-satisfied, modern cynicism" throughout like so many of the other guides we've had in Rome recently. I highly recommend this tour.
