Origin and history

The Dolmen de la Bie, also known as Pierre-Levée de la Dehors or Pierre de la Pie, is a megalithic vestige located at the Rochereau in Vienna (New Aquitaine). This monument, dated from the Neolithic, consists of an imposing sandstone cover table measuring 6.40 m long by 5 m wide. Originally, it was based on six orthostats, but only three remain today, two of which are still standing. The remaining blocks, scattered on the ground, could be debris from the original pillars. No archaeological material was associated with this site.

Ranked Historic Monument by order of 10 September 1945, the dolmen is today in ruins. Its structure suggests that it could have included a peristalith, although this hypothesis is not confirmed. The slabs, all in sandstone, bear witness to the megalithic construction techniques of the time. The site is listed in the Vienna megalith inventory, but its precise history and original use remain unknown.

The dolmen is located precisely at the following address: 3 Rue des Roches, 86170 Champigny-en-Rochereau. Although its location is considered "a priori satisfactory" (note 6/10), it does not have detailed archaeological or historical data. The monument illustrates the importance of megalithic sites in the region, often linked to funeral or ritual practices during the Neolithic period.
