Vestige néolithique dressé en Beauce, ce dolmen de Tillay-le-Péneux témoigne d'une spiritualité funéraire vieille de cinq millénaires, classé Monument Historique depuis 1979.

On the edge of the Beauce plain, at Tillay-le-Péneux, a special silence envelops the stone slabs of the local dolmen - one of the few megalithic remains preserved in the Eure-et-Loir département. In a region long devoted to cereals and arable farming, the presence of this funerary monument is a reminder that, long before its wheat cathedrals, Beauce was a densely populated area inhabited by organised Neolithic populations with an elaborate symbolic thought process. What makes this dolmen so special is precisely its persistence in a landscape shaped by millennia of intensive agriculture. Where so many similar megaliths have been dismantled to clear the fields or provide building materials, this one has survived, protected as much by its sturdiness as by local memory. Its large sandstone slabs, typical of late Middle Neolithic constructions, form a burial chamber whose refined architecture contrasts with the flatness of the Beaucerain plateau. A visit to this dolmen invites a rare form of contemplation. It is not a spectacular monument in the usual tourist sense, but a place charged with an authentic presence. Approaching the orthostats, putting your hand on the covering table, imagining the funeral and community rites that took place here between the 4th and 3rd millennia BC: the experience is intimate, almost philosophical. Prehistory buffs, photographers in search of low-angled light at dawn or dusk, and curious walkers will all find something to suit them. The surrounding countryside, typically Beauceron, offers 360-degree views. In spring, when the surrounding fields turn green, the contrast between the cold minerality of the megaliths and the gentle vegetation of the plain is particularly striking. In autumn, under the slanting light at the end of the day, the stones take on golden and ochre hues that reveal the full texture of the rock.
The dolmen at Tillay-le-Péneux belong to the family of simple dolmens or single-chamber dolmens, the predominant type in the Paris Basin and the regions bordering the Beauce. Its structure is based on the fundamental principle of the megalith: vertical slabs (orthostates) sunk into the earth and laid out in a rectangular or slightly trapezoidal plan, supporting one or more horizontal slabs forming the roof table. This highly efficient construction system enabled these monuments to survive for thousands of years without major collapse. The materials used are typical of the local resources available in the Beauce region: blocks of sandstone or hard limestone, extracted from seams outcropping in the subsoil of the region or transported from nearby geological formations. The quality of the selection of slabs testifies to the Neolithic builders' precise knowledge of the mechanical properties of the rock. The surfaces of the orthostats may show traces of polishing or symbolic engravings, motifs found in other dolmens in the Paris Basin, although their state of preservation varies according to exposure to the elements. The whole complex originally lay under a mound of earth and dry stone, of which only residual traces remain after centuries of erosion and cultivation. The burial chamber was accessible via an entrance corridor, sometimes enclosed by a perforated slab known as a 'porthole', symbolically allowing the passage of souls or new deceased. The size of the chamber, estimated at between two and four metres in length and one to one-and-a-half metres in internal width, is consistent with the architectural standards of Beauceron dolmens from the same period.
