Heart of the Valnerina. The town’s coat of arms, three castles, recalls the days when Vallo’s Swabian overlords ruled the roost in Umbria. Even Vallo’s castle is now a hoary ruin. From the river bridge there are quiet walks along the reaches of the Nera. A more strenuous expedition on foot is east over the Coscerno range of hills to Roccaporena (birthplace of Saint Rita) and Cascia (see Eastern Appenines).
