The river Palhères flows through Villefort on its way down from Mont Lozère. It goes through one of the two mismatched Gothic arches of Saint Jean bridge. This humpback bridge dates from the 14th century. Two rivers flow through the centre of the village, under Place du Bosquet. Having become unsanitary after being used as drains and latrines, they were vaulted over for reasons of hygiene in 1934. This created both the square and Rue des Jardins.
