After the operation, 1105 structures have been identified, spread over the entire area. This high figure is linked to the existence of a network of ditches which cut off the land in conjunction with a clearly identified Napoleonic patch on the ground. All of this seems to be linked to major drying works in the sectors bordering the Deûle, which were gradually introduced in the 19th century, which are repairing the landscape. These networks are very frequently observed in the Weppes sector. Previous occupations on hold mainly concern Prehistory, ancient times, the High Middle Ages and some elements attributable to the lower Middle Ages and the Moderne era. A series of 48 lithic elements from the filling of an isolated structure, despite the absence of microliths, evokes mesolithic elements. Despite its taphonomic context, it is of interest in the scarcity of sites discovered for this period in the region and confirms the potential of sites preserved in this sector of the Deûle Valley, which has already been suggested in previous operations. The ancient time is partly represented by furniture resulting, in small quantities, from the filling of ditches; their tracks do not reflect a structured occupation. The date of this furniture covers a wide period of time: mid I — II. J.-C. Two phenomena differ from this: the discovery on the municipality of sants of a structured set consisting of a long pit with a chablis and 2 buildings partially discovered. The pit delivers abundant ceramic furniture dated from the D2b tene, unfortunately the buildings are not dated. The second spot consists of the discovery in the municipality of Haubourdin of 2 funeral structures\ textendash a sepulture and an attachment pit\ textendash dated from the second half of the second century, seemingly isolated, but not without recalling the discovery carried out in 1890 when the bridge on the Tortle Canal was built and refers to the likelihood of necropole in the sector, probably in part destroyed today. The occupation of the end of the mesovingian era appears\ “_blank”, after a gap of several centuries, to be truly structured and exploitable. An archaeological site is present, partially exposed on the western edge of the area with a visible extension of the area outside the perimeter. All the remains, consisting of 6 silos, pits and some pole holes, clearly show the presence of domestic occupation on this part of the area. Alto-medieval ceramic furniture, consisting of around 100 pieces of fragments, dates back to the mesovingian era and persists in the first half of the 8th. The low number of pole holes and therefore the absence of a building after diagnosis may be due to the large mesh size of the network of ditches, which is not conducive to the detection of small structures, unless they are located to the west outside the area. No caban bottom has been identified. The organisation of the site therefore remains difficult to establish to date, but the remains, in particular the set of silos, show a satisfactory conservation status probably linked to the presence of a level of silt which sounds them. The lower Middle Ages is more anecdotal, only a few ceramic elements have been collected in large ditches, taken from the Napoleonic cadastre; the same applies to ditches that have delivered modern ceramics.
