Lauzerte (French pronunciation: ​[lozɛʁt]; Languedocien: Lausèrta) is a commune in the Tarn-et-Garonne department in the Occitanie region in southern France. Etymology of the name: Two interpretations include the possible Latin root of “Villaserta” and more likely, the Gallic root, “lauzes”, flat stones used as paving or roofing, and “erta” from the local Occitan dialect, meaning hill, thus Hill of Stones. The fact that the barbican was exploited as a quarry supports this derivation.
