Saint-Flour is a commune in the Cantal department in the Auvergne region in south-central France. Its inhabitants are called Sanflorains. The upper city of Saint-Flour is located on the abrupt volcanic dike Planèze, the lower city (ville basse) extends on the banks of the Ander. There are numerous dolmens in the neighborhood and scattered traces of Bronze Age occupation. Roman occupation is signalled by two Roman villas of middling importance, one near the railroad station, the other a modest Augustan-age villa near the hamlet of Roueyre, part of Saint-Flour.
The Roman name of this small vicus was Indiciacum or Indiciacus, which evolved into Indiciat in the sub-Roman period, a reference to the landmark of Planèze.
