Discovering Rome’s Architectural and Historical Marvels
This tour is designed for travelers who crave more than just a quick glance at Rome’s iconic landmarks. It offers a layered exploration: starting with the Pantheon, one of the best-preserved monuments from ancient Rome, and moving into underground areas few visitors get to see.
The Pantheon: A Wonder Beneath the Dome
Your journey begins at the Pantheon, a marvel of engineering with a history dating back nearly 2,000 years. The guide will walk you through its origins—built by Agrippa between 27 and 25 BC, then reconstructed by Hadrian around 118-125 AD, this structure boasts a massive dome of 43.3 meters in diameter and the iconic oculus that bathes the interior in natural light.
While many visitors admire this building from outside, this tour offers a detailed look at its interior details, including the marble and basalt construction, and the role it played as a temple and later as a church. The guide’s storytelling makes the history come alive, sharing insights that aren’t always obvious to casual visitors.
Exploring Raphael’s Tomb and Architectural Details
One highlight is visiting Raphael’s tomb inside the Pantheon, offering a rare glimpse into the life of one of Rome’s most celebrated artists. Their guide might mention Raphael’s significant influence on art and how his tomb remains a point of fascination for art enthusiasts.
Trevi Fountain and Its Hidden Depths
After the Pantheon, your route takes you through charming cobblestone alleyways toward the Trevi Fountain. Known worldwide, Bernini’s marble sculptures and the fountain’s grandeur are breathtaking. But what makes this experience unique is the underground exploration beneath the fountain.
Here, you’ll discover Vicus Caprarius, the City of Water, an archaeological site that reveals remains of ancient Roman aqueducts and the passages underneath the fountain. As one reviewer noted, it’s “an impressive archaeological area” that adds a new dimension to understanding Rome’s water engineering.
