The main village, Pont-de-Montvert (870 m altitude) at the base of the south-facing slopes of Mont Lozère, has retained the stony granite-built traditional aspect of its closely built centre, surrounding by outlying hamlets. The village is named for its hump-backed bridge (en dos d'âne) that spans in a single arch the swift-flowing Tarn— here near its source. The bridge is guarded by a defensive tower at the village end, now with a more amiable function: village clock. Medieval in aspect, bridge and tower date to the 17th century.
