This layout is the only one from the Celtic period known to us. The spatial and social organisation clearly shows the strong structure of Gallic society, indisputably hierarchical. The choice of the Bronze Age tomb as the point of reference for planning the land on which the village was built indicates decision-making by a person in authority, as does the social allocation of the quarters, with account taken of the geographical, geological and climatic constraints. It was occupied for a relatively short time, so the layout has remained clear despite later rebuilding. Because the later buildings used the same footprints, individual plans and the basic layout were not obscured. It is for this reason that several groups of structures, varying in number according to the status of their inhabitants, can be discerned individually around each of the courtyards. The southwest sector, home to the blacksmiths and coppersmiths, provides a good example.
