Norcia, traditionally known in English by its Latin name of Nursia, is a town and comune in the province of Perugia in southeastern Umbria. Unlike many ancient towns, it is located in a wide plain abutting the Monti Sibillini, a subrange of the Apennines with some of its highest peaks, near the Sordo River, a small stream that eventually flows into the Nera. The town is popularly associated with the Valnerina. It is a member of I Borghi più belli d'Italia.
