Introduction
If you’ve ever dreamed of walking above a real Roman arch for free, Walking Ancient Rome is exactly the kind of hidden experience you will love. What follows is the complete story of my visit to the Church of San Tommaso in Formis, a rare place where history, chance, and curiosity come together in the most unexpected way.
A Hidden Roman Surprise
Walking Ancient Rome begins on the Celio Hill, right next to Villa Celimontana, where the small and often-closed Church of San Tommaso in Formis quietly hides one of Rome’s most fascinating secrets. After several attempts, I finally found it open—and as the saying goes, fortune favors the bold.
As soon as I stepped inside, a friendly “good morning” and a respectful smile were enough to receive permission to explore. Then, quite surprisingly, I was invited to climb up to a viewpoint connected to the Arch of Gallienus, one of only two surviving gates from the ancient Servian Walls.
Climbing the Arch of Gallienus
Furthermore, reaching the top of this ancient structure felt surreal. Standing above the arch—an authentic Roman architectural element dating back more than two millennia—I could admire a view I had been trying to see for years. The panorama opens over a stretch of the city that blends archaeology, history, and the everyday life of modern Rome.
For context, the Arch of Gallienus originally served as Porta Esquilina of the Servian Walls. Even though it is not officially advertised as a viewpoint, access may occasionally be granted by the church staff, making the experience rare and unforgettable.
Walking Ancient Rome, When to Visit:
Useful Information and Opening Times
Additionally, it is essential to know that the church is not always open. Typically, San Tommaso in Formis opens on Sundays from 10:00 AM, although the schedule may vary depending on the custodians on duty.
Therefore, if you want to try your luck, the best strategy is:
- Visit on Sunday morning
- Enter politely
- Greet the staff warmly
- Ask if you may look around
With some kindness and a bit of luck, you may also experience Walking Ancient Rome firsthand—standing above a Roman arch at least once in your lifetime.
Why This Experience Matters
Moreover, discovering places like this goes beyond sightseeing. It is about connecting physically with Rome’s ancient layers—sometimes literally by walking on them. Walking Ancient Rome is not a metaphor here; it captures the essence of exploring lesser-known monuments that still breathe history.
This tiny church, its unexpected access, and the panoramic view from the arch collectively create a truly special moment, one that most visitors will never get to see.
