In the municipalities of Laon, Chambry and Barenton-Bugny (Aisne), the 150 hectares of the Pôle d’activités du Griffon (Griffon Industrial Estate) were the subject of archaeological testing by the City of Laon and the Department (County) of Aisne between 2006 and 2022, followed by 5 preventive excavations on nearly 13.5 hectares. These excavations were carried out by the Department of Aisne in partnership with Inrap. Firstly they concerned 10 sites with agro-pastoral and industrial activity (sectors A-B’, C, D, G-G’, H-H’, K, L, M-M’-M’, N and O) which developed mainly between La Tène C1 at the end of the 3rd century/ beginning of the 4th century A.D. Also the excavations concerned 7 necropolises (sectors B, E, F, I, J, P and Q) from the end of La Tene C1 to La Tene D2. Four additional sectors (3 agrarian sectors R, T and U and a Gallo-Roman necropolis S) were detected during the 2022 testing. The settlement sites allow us to understand the anthropic formation of the landscape of the Champagne plain north of Laon, with the foundation of continuous and discontinuous occupations, times of strength and weakness and desertions, all within 15 chronological horizons, grouped into eight occupation sequences, from the Neolithic to the years 250/270 to 300/320. After a single trace of human presence in the Neolithic (sequence 1), the first structured occupations are open, modest and isolated at the Final Hallstatt / Early La Tène (sequence 2, sector N) and then at La Tène C1 (sequence 3, sector D). Human society’s hold on the land was increasing between La Tène C2/D1 and La Tène D1b/D2a (sequence 4), where sectors C, L, M and A-B’-U were associated with the vast establishment of sector G-G’. In sequences 5 (from La Tène D2b to -5/-1) and 6 (from -5/-1 to 40/45), the occupation of the land was laid out according to a grid of farms with a less pronounced hierarchy (sectors A, G, H and M). Sequence 7 (from 65/70 to 120, or even 150 approx.) is marked by the creation of a new enclosed area (sector M’) and the development of a site with industrial activity (sector K). During the final sequence (sequence 8; from 250/270 to 300/320), the occupations were still part of the first century’s grid but reduced within much smaller areas. The 8 funerary complexes, for their part, total 96 burials, ranging from 3 tombs (sectors B, J and Q) to 62 tombs (sector F). They developed mainly from the end of La Tène C1 to La Tène D2b (7 necropolises with 92 tombs, including 11 monumental sites, accompanied by 11 pits with offerings). A single funerary group of 2 or even 4 tombs, as well as an isolated tomb (but located in the Gallic necropolis P), have been recorded. These funerary complexes add to the issue of characterising funerary forms from the Second Iron Age in Picardy, identification of the operational chain(s) and choice of the use of the funeral space when backfilling of the sepulchral pit. The furniture deposited with the deceased in particular allows an approach to the hierarchy(s) and possible long or medium-distance trade. These necropolises raise questions about the evolution of the population from La Tène C to La Tène D, but also the occupation of this land and its use. Indeed, the relationship appears complex between settlements, which cover an interval of nearly a millennium, and necropolises, which are on the contrary concentrated over a much shorter period (less than 200 years, except for the few Roman tombs). The linking of funerary groups and corresponding contemporary settlements is all the more delicate as the number and size of these occupations seem insufficient to require such funeral activity.
