The isolated structure of the Neolithic site 19, Lake Chalain (Jura, France) dendrochronological study of oak pilings (Quercus sp.)
At least ten contemporary villages existed along the western shore of the lake of Chalain from the 32nd to 30th centuries B. C. Chalain 19 (CH19) is the most extensively excavated site to date and the first to permit an analyse of the internal organisation of these villages.
Two sectors can be differentiated in the village : the first is densely constructed whereas the second one contains only one architectural structure.
Dendrochronological study confirms this is an isolated construction which had been rebuilt and consolidated numerous times. This structure raises a number of questions for which we advance several research hypotheses.
