Fescennia or Fescennium was an ancient city of Etruscan/Faliscan origin, which is probably to be placed immediately to the north of the modern Corchiano, 6 miles (9.7 km) north west of Civita Castellana, in central Italy. The Via Amerina traverses it. At the Riserva S. Silvestro, walls exist. At Corchiano itself, however, similar walls may be traced, and the site is a strong and characteristic triangle between two deep ravines, with the third (west) side cut off by a ditch. Here, too, remains of two bridges may be seen, and several rich tombs have been excavated.
