The patron saints of Narni are Saint Juvenal, the town's first bishop, celebrated on 3 May in the cathedral dedicated to him, and Saint Cassius, co-patron, celebrated on 4 July.
The vast municipal territory, made up of numerous hamlets, also holds its own distinct devotions: at Narni Scalo, the town's main outlying district that grew up around the Linoleum industrial plants in the 20th century, the patron is Saint Linus, while the hamlet of La Quercia is known for the sanctuary dedicated to the Madonna della Quercia. Every October, the Chestnut and New Wine Festival is also held. The town also holds the Bridge of Augustus and the Albornoz Fortress.
