Starting Point and First Impressions
The tour begins at Vicolo del Puttarello, 25, a typical narrow Roman alley that sets the tone for the adventure ahead. It’s a quick meeting at the entrance of the Vicus Caprarius archaeological area, which is tucked away and often overlooked by visitors rushing past the Trevi Fountain. The appeal here is the chance to explore less crowded spaces with a guide who can unlock stories hidden beneath the modern city.
Exploring Vicus Caprarius
The main part of the tour, lasting about 40 minutes, takes you through three sections of ancient Roman ruins. This site, known as the “City of Water,” is a fascinating archaeological zone that reveals how water was managed and transported in ancient Rome.
We loved the way guides explained how the water flowing from the Trevi Fountain continues to filter through the ancient masonry, highlighting Rome’s sophisticated aqueduct system. This isn’t just about pretty ruins; it’s about understanding how water shaped Rome’s luxurious lifestyle and urban development.
The Underground Marvels
Descending into the underground chambers, you’ll see relics like ancient coins, amphorae, and the head of Alessandro Helios — a striking piece that underscores the artistry and craftsmanship of the Roman elite. The 800 coins discovered here serve as a testament to the long history of offerings and prayers beneath the city.
The tour also showcases the polychrome marble coverings, which once adorned the floors and walls of Roman homes, giving a glimpse into the opulence of the luxurious domus that once stood here. The African amphorae, called spatheia, were used for transporting oil and are a reminder of the trade networks that fed Rome’s grandeur.
