Origin and history
The covered driveway of the Blanc-Val, located in Presles in Val-d Alerté, Mayor M. Laval undertook excavations and had the site classified in 1951. The building, vandalized several times, was restored in 1956.
Aisle, facing north-north-west/south-south-east, 6.50 m long, with a 5.30 m bedroom and an antechamber of 1.20 m. Its local limestone slabs, broken by ploughing, suggest an original height greater than 1.45 m. The entrance, pierced by a circular orifice, could result from a broken slab or a two-part construction.
The excavations revealed the bones of about 21 individuals (adults, a teenager and a child), dated Neolithic, as well as funeral furniture (haches, pearls, blades) attributed to the Seine-Oise-Marne culture. These remains, preserved at the Institute of Human Paleontology in Paris, illustrate the collective rites of the time.
The absence of cover tables suggests protection in wood or thatch. The site, typical of megalithic burials, provides insight into the Neolithic communities of Île-de-France, their beliefs and their social organization around the dead.
