Vicus Caprarius

Vicus Caprarius, the City of Water

If people tell you that you can go underneath the Trevi Fountain, they are not being completely honest.  You can go under part of the Trevi District, but it is not completely under the fountain.  Still, it is definitely worth the 4 euro that it costs to visit this archeological site.  It was discovered in 1999 by accident during renovations of the Trevi Cinema.  It was opened to the public in 2004.  It is believed to have been built as early as the first century AD.

Agrippa inaugurated the Aqua Virgo in 19 BC and it is still in use today, supplying water to the Trevi Fountain and several other fountains in Rome.  There are 11 aquaducts in Rome, but only this one remains in continuous use today.

To visit the underground Water City, follow signs near the Trevi Fountain that lead you to the site.  The entrance is located at Vicolo del Puttarello 25, in Rome.  It is only a few minutes' walk from the Trevi Fountain.  

We visited Rome in March of 2025 and were able to purchase tickets to Vicus Caprarius an hour in advance for 4 euro each.  Their official website is here:  Vicus Caprarius  The area is very small and does not take long to walk through.  A guided tour is not needed, as you can quickly walk through the City of Water yourself and read the plaques.  

The famous Trevi Fountain is above ground.  The City of Water is below ground, although not directly below the fountain.  When visiting the City of Water, you go down metal stairs that descend from the ground level 9 meters down to the archeological site.
