Discover hidden underground sites of Assisi with this 2-hour guided tour, exploring Roman ruins, frescoes, and St. Francis' prayer spots.
Exploring Assisi often means marveling at its above-ground religious monuments and stunning basilicas, but there’s a whole other world beneath the surface that many visitors overlook. The 2 Hour The Secrets of Assisi Underground Walking Guided Tour offers a fascinating peek into the city’s lesser-known underground layers—Roman ruins, crypts, and secret prayer spots—all wrapped in an intimate small-group setting.
What makes this experience particularly appealing is the chance to see Assisi from a different perspective—beneath the bustling streets and famous landmarks—while uncovering stories that have remained hidden for centuries. The tour’s highlight is the well-curated itinerary, led by guides who bring history to life with deep knowledge and engaging storytelling. However, keep in mind that entrance fees for some sites are extra, so budget accordingly if you want full access.
This tour is ideal for history buffs, art lovers, and those eager to go beyond the typical tourist trail. If you’re curious about Roman foundations of Assisi or want a more personal, narrative-driven experience of St. Francis’ spiritual spaces, this is an excellent choice. It’s especially suited for small groups seeking a relaxed, engaging exploration—and for travelers who don’t mind paying a little extra for a richer experience.

The tour kicks off at the Cathedral of San Rufino, a central and accessible location in Assisi’s charming piazza. Here, visitors are introduced to the history of the crypt of San Rufino, located beneath the nave. The crypt is a particularly evocative spot—small, dark, with 11th-century frescoes that give a glimpse of medieval religious art, and a Roman sarcophagus illustrating the myth of Selene and Endymion.
According to those who’ve taken the tour, this part of the experience feels very intimate. One reviewer, Clifton C., mentioned, “The guide was excellent. Very knowledgeable and explained so much. Answered many questions. Walk was easy.” The crypt served as a quiet retreat for St. Francis himself, making it a special place for those interested in his life and practices.
Next, the tour visits the Museo Diocesano e Cripta di San Rufino. Here, visitors get to explore the remains of a Romanesque cloister and the crypt of the 11th-century basilica. The frescoes and artifacts on display offer a vivid sense of the religious artistry of that period, as well as insights into the religious and civic life of medieval Assisi.
One of the highlights is the Roman sarcophagus housing the myth of Selene and Endymion. The frescoes, rare for coeval art, help bring the past to life, and the atmosphere of the crypt itself feels like stepping back in time. Reviewers appreciate the guide’s ability to contextualize these relics, with Jane K. noting, “Clair was an excellent tour guide! Armed with her deep knowledge of art, she delivered a wonderful appreciation for every painting and artifact now confined to the underworld!”
The most exciting part of the tour for history lovers is the visit beneath the current town square—the Roman Forum. Excavated in 1836, these ruins reveal the city’s ancient Roman roots. Visitors can see the base of the temple dedicated to Minerva, the podium with magistrate seats, and the foundations of a tetrastyle temple dedicated to Castor and Pollux.
You’ll be walking in the same space where Roman citizens once gathered, and many find the scale and preservation of these ruins quite impressive. The underground remains serve as a tangible connection to Assisi’s layered past, a city that has transformed over centuries but still preserves its Roman origins beneath modern streets.
The small size of the group (maximum 15 participants) ensures that you’re not just a face in the crowd. Our guide, Clair, was praised for her ability to make ancient artifacts relatable. She explained how these ruins fit into the broader story of Assisi’s development and answered questions with enthusiasm.
The walking pace is gentle, with plenty of time to observe and absorb the details. The tour lasts approximately 2 hours, making it an ideal option for travelers with a packed itinerary who want a focused, enriching experience.

This experience is perfect for travelers who want to go beyond the typical Assisi sightseeing. It especially appeals to those with an interest in ancient Rome, religious history, or art, as the sites feature well-preserved frescoes and artifacts.
It’s also ideal for visitors who appreciate small-group tours, as it offers a more relaxed, detailed exploration with a knowledgeable guide. If you’re interested in the spiritual side of Assisi, you’ll find the crypt spaces—like the one where Francis himself prayed—particularly meaningful.
