The Middle Bronze Age site of Berstett Langenberg (Lower Rhine), cross-referenced approaches

Excavated in 2018 as part of the western bypass of Strasbourg, the Berstett Langenberg site of nearly two hectares (site no. 5.6 of the project) has revealed occupations dating from the Late Neolithic to the Final La Tène period. The Bronze Age occupation is characterised by 43 features spread over almost the entire area, while the 31 Middle Bronze Age features include ten pits, storage pits (11), two possible excavated buildings, three slits and five windfalls. No buildings were found, but areas devoid of features surrounded by pits suggest the location of buildings, as do the remains of cob (earth and wood architecture). The large quantity of ceramic remains uncovered (160 vessels), as well as several radiocarbon dates have made it possible to better characterise the typochronology of the ensembles for the Bronze D and the transition from Bronze D to Bronze D. Biogeochemical analysis of the inner walls of ten vessels has revealed animal fats, as well as traces of vegetable oil (Brassicaceae) or resin (Pinaceae). In addition to the large quantity of pottery, which makes the site a reference point, other objects unearthed (lithics, fauna) provide supplementary information as to the late Middle Bronze Age settlement for which little is known in eastern France.
