The enclosure of Lauwin-Planque, located in Nord - Pas-de-Calais has been excavated in 2002 and 2003 by the service archélogique of Douai under the direction of Christian Séverin and with the help of Françoise Bostyn (INRAP). The site, important for regional surveys, offers sections of moats and trench of palisades’ groundworks, certainly part of an enclosure. In the north, digs show the map of a dwelling. In the east, a big pit has been interpreted from its ununsual lines, as a pit used for loam extraction. Ceramics come from 3 main structures : a section of moat , a trench of palisade groundwork and from the big pit. The series comprises 7250 sherds and weighs 54,235 kg. 47 poteries and 27 disks of terra cotta have been individualized. This technological and morphological study has led to a better definition of the regional context by the attachment of Lauwin-Planque to the group of Spiere, created in Belgium by Bart Vanmontfort in 2001. This group is different from other synchron cultures : Michelsberg and Chasséen Septentrional. It is defined by the absence of caracteristic shapes from Néolithique moyen II : Beecher from Michelsberg and carinated poteries from Chasséen Septentrional. It is also characterized by the use of combined temper : particles of burnt and pulverized flint in association with vegetal inclusions. Two approaches have been chosen to study this collection : technology and morphology. By the study of « macrotraces », we can recreate « chaînes opératoires » of building . This series is characterized by an important technical variability andpoor workmanship. Morphologically, ceramics are not standardized. After obtaining these first results, we can now start thinking about the transmission of know-how.
