The Fontana del Borgo,dating back to the 16th century, also known as the Pietrosa, is a splendid fountain listed as a national monument. Originally used as a public fountain, the fountain has been maintained several times over the centuries until it was completely overwhelmed by surrounding construction work and the filling of the Pietrosa Valley in 1922. Today the Fonte del Borgo is only partially visible, but it can still be visited despite being below street level. It is a green oasis interspersed with a long series of decorative arches flanking the gable pediment. The fountain is still functioning and spring water can still be seen gushing from 6 stone masks.The carved masks represent human faces equipped with lion's manes from whose mouths gushes water that goes to feed the pool below. If the structures are in good condition, the same cannot be said of the surfaces: both the access staircase and the floor are covered with uncultivated vegetation, which in any case do not detract from the beauty of the monument.
