Origin and history
The covered driveway of Aizier was a megalithic burial of Neolithic, destroyed in the 19th century during road works between Aizier and Bourneville. Only a pierced slab, serving as a separation wall in the corridor, was preserved. Measuring 1.8 m wide and 1.5 m high, it has an oval and conical hole (0.53 m outside diameter), carefully cut. Originally buried 2 m deep, it was extracted and integrated into a property wall before being rediscovered a century later.
The slab was first reported in 1878 by Georges Biochet, who published his observations in Norman bulletins. He also mentioned an adjacent stone stopper, still present in the slope of the road. In 1896, Léon Coutier used this data in his inventory of the megaliths of the Eure. Rediscovered in 1979 by Jean-Marin Barret, the slab was studied and installed near Saint Peter's Church, its current location.
Skulls were exhumed in 1878 at nearby foundations, but their origin (neolithic burial or medieval cemetery) remained unknown. Ranked a historic monument in 1999, the slab and its potential remains are protected in situ. His hole, interpreted as a symbolic or functional passage, illustrates the funeral practices of the final Neolithic (2500–1800 BC).
