The tour begins at Piazza di Spagna, where the guide explains the origins and significance of the Spanish Steps, including a surprising detail about their naming. From here, the group visits the first fountain of the tour, which still receives water from an ancient Roman aqueduct built in 19 BC. The guide shares insights into Rome’s water systems and how they influenced the city’s development.
Standing at the Spanish Steps, visitors gain context about Rome’s urban history, setting the stage for the journey through its aqueducts. The starting point offers a chance to appreciate the blend of modern and ancient architecture that characterizes the area.

After the initial introduction, the tour follows the underground pathways of Rome’s aqueducts. The guide points out sections of the aqueduct that are visible between modern buildings, illustrating how the ancient infrastructure remains woven into the city’s fabric. During the walk, there are opportunities to go underground and see the aqueduct’s water flow up close, providing a rare glimpse into ancient engineering.
Most of the aqueducts are mostly underground, and the guide carefully explains their construction and purpose. The path leads toward the monumental endpoint—the Trevi Fountain, which is still fed by one of Rome’s original aqueducts. Visitors get to witness the water source and its flow, connecting the past with the present.
The highlight of the tour is the Trevi Fountain, where visitors learn where its water originates and how Romans have maintained the fountain’s operation for over two millennia. Unlike typical visits, this tour emphasizes the aqueduct that supplies the fountain, making the water’s journey from ancient source to majestic display a core part of the experience.
Along With the fountain, the tour takes a detour away from crowds to explore an underground water reservoir built by the Romans more than 2000 years ago. This site reveals the sheer scale and sophistication of Roman water management, and guides provide context and stories that deepen understanding.
