The dwelling development process is analysed in detail : grouped native dwellings as from La Tene D1, urban development as from the 2nd century A. D. Six stages are explored. Annexed to the analysis are detailed descriptions of dwelling structures for all different periods, with a catalogue of associated movables items. Finally the studied relationship between the various excavated areas correlates the stages applying to the sanctuary, and to the habitat. The “Moulin des Hayes” and “Sablons” sites can therefore find their places in their regional historical context.
