Rome – the Eternal City, wasn’t built in a day! Nor is what you see today the whole city. So much of it is… underground. On this tour you will discover how Rome was really built: in layers over several hundred years. Due to the damage caused by wars, fires, floods and other disasters, Rome was rebuilt upon itself time and again. 

Your tour begins at the fascinating Basilica San Clemente, where you’ll uncover the mysteries of subterranean Rome.  San Clemente is a medieval basilica with stunning gold mosaics – in itself a true treasure. But hidden below is another church, built on a pagan temple – built on a Roman house! You’ll see frescos that have survived since the 8th century and learn about the early church and the martyrs depicted on the walls. You’ll hear why so many churches in Rome were built on top of Pagan temples. You’ll learn all about the mysterious cult of Mithras in the eerie temple beneath, and see the surviving altar piece of Mithras and the Bull. Your guide will walk you through the first century Roman apartment and tell you all about a day in the life of an ancient Roman! 

Returning to the surface, you’ll head outside the ancient city walls to one of the largest catacomb complexes – the ancient burial grounds of the illegal, persecuted Christians in Rome. You’ll descend into this dark maze of galleries lined with hundreds of rectangular graves – now empty niches thanks to the Barbarian raids. You’ll learn all about the burial rituals and decode the secret messages in the frescos and carvings on the terracotta and marble gravestones. You’ll see the tiny oil lamps by which the gravediggers worked and see their pick axe marks and scrapes in the soil and tufa rock around you. A truly unique, fascinating and awe-inspiring experience. 

Then you’ll return to the surface, be driven back to the city center to enjoy the hustle and bustle of daily life in modern Rome – with the knowledge that another three cities exist beneath your feet!

All LivTours Semi-Private Group Tours are limited to 6 guests per tour guide. Our commitment to maintaining our uniquely tiny group sizes can sometimes be a little tricky, mathematically speaking. For example, we want to ensure that traveling families and friends can tour together so on rare occasions we may add one or two guests in order to not split groups. On that same note, you may also find yourself on tour with less than six people! We thank you for your understanding and flexibility.
