Rome: Trevi Fountain & Underground Aqueducts Tour

About this tour

The Aqua Virgo aqueduct, functioning since antiquity, remains the hidden backbone of this iconic landmark.

What to expect

Start topside at the Trevi Fountain where your guide decodes its Baroque design, baroque sculpture, and the engineering feats that made it possible. You'll enter the restricted basin area—roped off to ordinary visitors—for an unobstructed view of the fountain's mechanics and intricate stonework. Then descend into Vicus Caprarius, a subterranean site revealing Roman apartments, shops, and the operational aqueduct channel carved into bedrock. The contrast between bustling modern Rome above and the silent, preserved remnants below makes the underground section feel like stepping into a time capsule. Expect modest lighting, narrow passages, and stone surfaces worn smooth by centuries of flowing water.
