The layout of certain buildings (villae) is known, although it is often incomplete (for instance at Saint-Clément). Research has too often focused on the living quarters to the detriment of parts serving an economic function (agricultural part). The most luxurious villae had rooms with under-floor heating (Rouveret-la Faïsse), walls decorated with painted plaster (Finiols, Rouveret-la Faïsse, etc.) and thermal baths (Saint-Clément).
The site of Rouveret-la Faïsse had an economic sector. The structure reserved for the storage of agricultural produce leant against the living quarters (vases for storing cereals were discovered). An area dedicated to small-scale production of pitch has also been excavated.
The existence of other rural settlements is indicated by the discovery of vestiges (tiles, pottery) during surveys.
Agriculture and animal husbandry
That cereals were part of the staple diet has been proved by the discovery of millstones for grinding grains. Evidence of agricultural tools, such as hoes at Rouveret-la Faïsse, has also been found.
The territory of the National Park is part of a region of vast plateaux (Causses, Cévennes, Mont Lozère) suitable for animal husbandry. There is no doubt that this activity was already developed here in Antiquity. Pliny the Elder (1st century B.C.) extolled the quality of gabales cheeses, which were appreciated as far away as Rome.
