Vallo di Nera and the neighbouring Piedipaterno are situated in a particularly fascinating part of the Valnerina valley, because here a narrowing of the valley has created small plains and valleys furrowed by the crystaline waters of the Nera river and of its tributary, the Vigi.

As the town was nearly always under the rule of Cerreto of Spoleto, it is easy to deduct which periods were forunate or not for the fate of the village. In part, the town still preserves Romanic religious and municipal buildings dating back to the beginning of the Middle Ages. The church of Santissima Annunziata dell'Eremita is perhaps the most noteworthy example: the upper church is built in the shape of a Latin cross, while the crypt follows the form of a Greek cross. Nowadays, only a part of the church's central nave remains. More interesting is the series of votive frescoes dating back to the 15th and 16th centuries with decorate the interior.To the north of the town, on foot you'll reach the small township of Paterno, situated at 605 meters above sea-level, where you can visit the well-preserved Parrocchial church with its beautiful baptism fount inside.
