Visit to the Trevi Fountain Undergrounds

The visit to the Trevi Fountain underground is a lesser-known but at the same time incredibly suggestive tourist route. It is well known that wherever you dig in Rome you can find ancient domus, aqueducts and archaeological finds. The site beneath the Trevi Fountain is a prime example and well worth a visit.

The Vicus Caprarius, “the city of water”.

The underground archaeological site beneath the Trevi Fountain has been given the name Vicus Caprarius, or “city of water”. It was discovered between 1999 and 2001 during the renovation works of the former Trevi Cinema.

Excavations carried out in conjunction with the Superintendence for Archaeological Heritage of Rome brought to light a complex of buildings from the Imperial period, including the canals that carried water from the Acquedotto Vergine to the luxurious domus in the area, where the clear water of the Luigi countryside still flows at a depth of 9 metres from street level.

The antiquarium

Framing the archaeological site is the antiquarium, an exhibition of all the artefacts that have been found over the years during the excavations. These include an interesting number of coins dating from the 4th and 5th centuries AD, as well as objects of everyday use.
