In a city as old and large as Rome, there's bound to be interesting nooks and crannies that fly under the radar. As it turns out, one of those semi-secret spots has been hiding right under the noses of millions of tourists — beneath the Trevi Fountain, to be exact.

Federica, the local tour guide behind the Instagram account @livevirtualguide, recently surprised her followers with a video showing the little-known Roman attraction that takes visitors to the area underneath the Trevi Fountain.

Vicus Caprarius, known as the City of Water, is an ancient Roman apartment complex located beneath the city's Trevi district, including its famed fountain. The archaeological site dates back to the first century, but wasn't discovered until the late 1990s.

Today, visitors can head to the underground site for a glimpse at the homes of ancient upper-class Romans. The space also displays examples of the hundreds of artifacts that were found during excavation, including terra-cotta figurines, African pottery, mosaic tiles, and over 800 coins.

What makes this hidden gem particularly special, however, is the water that runs through it. At Vicus Caprarius, visitors will find pools that still fill with water, thanks to the Aqua Virgo, one of the 11 aqueducts of ancient Rome. This aqueduct is also the one that feeds into the Trevi Fountain, meaning the water you see in Vicus Caprarius will eventually make its way to the fountain for tourists to throw their coins in.

Tickets for this archaeological site are only four euros (about $4.73 USD). For more information on how to visit, check out the official website.
