Trevi District Underground guided tour at Vicolo del Puttarello 25

The Trevi District Underground guided tour is a walking and underground tour in Rome that combines a visit to the Trevi Fountain with access to excavated ruins beneath the city streets. The Trevi Fountain, completed in 1762 and designed by Nicola Salvi, is the largest Baroque fountain in Rome, fed by the ancient Aqua Virgo aqueduct that has supplied water to the city for over two thousand years. The tour pairs this above-ground landmark with a descent into layers of Rome that most visitors never reach.

At street level, the guide covers the history and iconography of the fountain, including the central figure of Oceanus and the tradition of coin-throwing that funds local charities. Underground, the tour moves through excavated remains dating to ancient Rome, where guides explain the successive building phases that have shaped the district from antiquity through the medieval period. Tickets cover the guided commentary throughout, entry to the underground site, and all included access fees. Group sizes and available departure times are listed at booking.
