Unearthing Rome’s Hidden Secrets: The Underground Rome Tour of St. Clement and Celian Houses

This private tour promises a fascinating journey beneath the bustling streets of Rome, revealing layers of history that many visitors never get to see. It combines visits to the Basilica of St. Clement and the church of Santi Giovanni e Paolo, along with explorations of underground houses, ancient streets, and hidden structures.

Exploring Rome’s Hidden Undergrounds: What You Can Expect

This tour offers a rare peek into Rome’s subterranean world, taking you beneath the surface of the city’s well-known streets. It’s a journey through time, revealing the layers of history buried beneath Roman architecture and urban life. From ancient homes to churches built atop older structures, the tour’s focus on underground sites makes it a unique experience — especially for those bored by crowded, surface-level sightseeing.

The tour kicks off at the Basilica of Santi Giovanni e Paolo on the Caelian Hill, one of Rome’s seven hills, which historically housed the residences of both high-class and middle-class citizens. Here, you’ll learn about the underground houses of Saints John and Paul, which date back to early Christian times. The guide will help you visualize how Romans once lived in these subterranean spaces, offering a tangible connection to the past.

Next, you’ll descend beneath the Basilica of San Clemente, a multi-layered church that’s a highlight of the tour. What makes San Clemente extraordinary is its complex stratigraphy—layers of history built on top of each other, from a Roman house to an earlier pagan temple and a late Roman church. Expect to see fascinating frescoes, ancient mosaics, and underground chambers that reveal how the site evolved over centuries.

Finally, the tour takes you up to the Caelian Hill, where you’ll explore the “House of John and Paul” underground, along with ancient streets and abandoned shops from earlier periods. This part offers a sense of Rome’s daily life beneath the grandeur of its famous monuments, showing what life might have looked like beneath the surface.

The Itinerary in Detail

Basilica of Santi Giovanni e Paolo

Starting here, you’ll discover the underground remains of the houses of Saints John and Paul, believed to be early Christian martyrs. The site is a beautiful example of how underground spaces can hold stories that leap across centuries. Reviewers have praised the way the guide recounts this history, with one noting, “Travel from Middle Age to Ancient times in just a few steps,” highlighting the remarkable layering of history at this spot.

While entrance tickets aren’t included, the site is free to visit. Still, it’s worth knowing that the ticket for the Basilica itself costs around 25 euros—something to factor into your planning if you wish to see the church’s interior as well.

Caelian Hill: A Glimpse into Roman Elite Residences

After exploring the basilica, you’ll walk (or drive) to the Caelian Hill, one of Rome’s original seven hills, rich with ancient aqueducts, temples, and noble residences. Here, you’ll get a sense of the high- and middle-class life of ancient Rome, with the added thrill of discovering the underground house of John and Paul. The guide helps bring this history alive, emphasizing the importance of the hill in Roman social and political life. This stop is short—about 20 minutes—but packed with insights.

Basilica of San Clemente: The Underground Treasure Chest

The highlight of the tour is the visit to San Clemente, which demands around an hour and 45 minutes. This church is a literal layered cake of history, with each stratum revealing a different era. Visitors often comment on the multiple layers of the church—from the Roman house to the early Christian basilica—and how the site encapsulates Rome’s constant evolution.

Expect to see frescoes from different periods, some dating back to the 12th century, and to learn how the church was built, destroyed, and reconstructed over centuries. The guide’s storytelling makes these layers tangible, transforming stone and fresco into vivid history lessons.

Underground Streets and Abandoned Shops

The final part of the tour involves wandering underground streets and exploring the remains of shops and homes. This section offers a glimpse into everyday Roman life that’s seldom visible above ground. As one reviewer mentions, “You will miss so much without a guide”, emphasizing the value of the expert narration in understanding these hidden spaces.
