Not far from the Colosseum, the Basilica of San Clemente offers a vertical journey through Rome’s layers of history. Beneath the present-day church lie a paleochristian basilica, a Mithraic temple, and even a Roman house, each one a testimony to different eras and overlapping cultures. Visiting this site means literally descending through the centuries, moving between pagan symbols and Christian frescoes in a dialogue between past and present.

In the charming Trastevere district, you can also experience the magic of underground Rome. Beneath the baroque Basilica of San Crisogono lie the remains of an ancient paleochristian church with mosaics, columns, and forgotten altars, all wrapped in a surreal silence that takes you back in time. A little-known gem, it offers a rare authenticity and a profoundly touching atmosphere.

Many local guides and cultural operators offer tours that combine several of these sites in a single experience: from the Roman houses beneath Palazzo Valentini, with multimedia reconstructions, to the ruins under Piazza Navona and San Giovanni in Laterano. During summer, some visits are also organised at night, making the atmosphere even more enchanting.

At the end of the day, The Caesar Roma is the perfect place to unwind after an intense day of discoveries — and an excellent base for exploring a lesser-known, quieter, and incredibly fascinating Rome.
