The Allée Sépulcrale at Bury (also known as the Bury gallery grave or the Allée de Saint-Claude) is a massive, semi-underground Neolithic tomb discovered in 1998 by a homeowner digging in their private backyard. Measuring nearly 20 meters long, it is one of the largest and most significant collective burials in the Paris Basin.

Key Details & Significance
The Discovery: Found on the grounds of a private property on the Rue de la Plaine Sainte-Claude. Because it was buried directly beneath a garden, it remained pristine and was not heavily damaged by modern agriculture or looting.The

Skeletons:
The tomb contained the exceptionally well-preserved remains of over 300 individuals.Extended Use: Excavations spanning from 2001 to 2007 revealed that the monument was used for over 1,500 years. It transitioned from a community tomb during the late Neolithic (circa 3500 BC) to the dawn of the Bronze Age.

Genetic Revelations:
Ancient DNA analysis of the bones revealed a remarkable scientific discovery. The tomb was used by two entirely distinct populations that lived side-by-side but had virtually no genetic overlap, highlighting a fascinating cultural dynamic in ancient Europe.

Architecture:
Unlike pure stone dolmens, the structure originally utilized a framework of wooden walls alongside stone slabs, including a notable limestone "porthole" slab.Because the site is located on a private residential lot, it is not open to casual walk-in visitors. The artifacts and detailed stratigraphic reports are managed by regional French cultural authorities and can be explored further through academic resources like the OpenEdition Journals Entry or the broader archaeological summary available on Anthropology.net.
