Ponte Fonnaia and Catacombs of Villa San Faustino

Ponte Fonnaia is a Roman bridge located near the ancient Via Flaminia in the stretch that connected Acquasparta to Massa Martana. Built in 220 BC and still in excellent condition, its purpose was to help travelers cross the stretch of the Naia river which, unlike today, which is dry, had a good flow of water.

In the following decades next to the bridge arose the so-called Grotta Traiana, a Christian catacomb near which developed a real structure made of tunnels and tunnels designed to accommodate the Christians who gathered to officiate their rites. It is a unique structure of its kind, not only in Umbria but also in neighboring ones.
