The town itself is a settlement that grew up around centuries of small castles and towers defending the right bank of the Nera river, 15km east of Terni and about 6km south of Ferentillo . The whole area is intensely green and is considered one of the beauty spots of central Italy.
Civilization is very much present, though.
In town the church of S. Bernardino goes back to the 9c, and outside the limits of Montefranco, at the Case San Pietro, one of the houses includes fragments of 9c sculpture and identifiable pieces of a 1c funerary monument. A proper website will eventually appear here, since I've been to Montefranco, if briefly.
