Dolmen dit La Pierre couverte
MonumentHidden Treasure
Sentinelle de pierre dressée depuis le Néolithique aux portes du Val de Loire, la Pierre couverte de Gennes compte parmi les dolmens angevins les mieux conservés, vestige silencieux d'un rituel funéraire vieux de cinq millénaires.
History
In the heart of the Saumurois region, in this land of white tufa stone where the Loire meanders most peacefully, the covered stone of Gennes stands out as one of the most enigmatic presences in Maine-et-Loire. This Neolithic dolmen, listed as a Historic Monument since 1980, is the embodiment of several millennia of collective memory, long before the first lords built their stone keeps and winegrowers planted their vines on the surrounding hillsides. What makes this monument truly singular is the raw power that emanates from its primitive architecture: massive orthostats - large slabs standing vertically - support a roof table that probably weighs several tonnes. The magnificent brutality of these stones, piled up by Middle Neolithic man, creates a striking, almost anachronistic contrast in a gentle, hedged landscape. The visit is more like a meditation than a mapped route. You walk around the burial chamber and see for yourself the technical feat involved in lifting such large blocks with no tools other than collective skill and human ingenuity. Archaeologists believe that successive burials may have been laid in these dolmenic chambers over several generations, making these structures not just a single tomb, but a genuine dynastic place of communal memory. The natural setting amplifies the emotion: the area around Gennes, crossed by the nearby Loire, offers a blend of golden Angevin light and the dense vegetation typical of the Loire valley. Photographers and walkers will find much to contemplate here, especially at low hours when the long shadows dramatise the contours of the ancient stones.
Architecture
The Pierre couverte de Gennes belongs to the family of single-chamber dolmens, the most widespread form in the Saumur and Anjou regions. It consists of a burial chamber bounded by several orthostats - vertically upright slabs forming the side walls and base - on which rests a large horizontal cover slab, giving the monument its vernacular name of "covered stone". This type of structure, sometimes preceded by a partially preserved access corridor, is characteristic of the Middle Atlantic Neolithic. The materials used are limestone or sandstone blocks, extracted from typical geological outcrops in the Loire Valley, notably tufa and Turonian chalk formations. These stones, although resistant, have been subjected to erosive action over five millennia: acid rain, freeze-thaw, plant invasion. Despite this, the overall structure has remained remarkably stable, testifying to the care taken to maintain the original architectural balance. The precise dimensions of the monument are typical of regional Dolmenic architecture: the chamber is probably between three and five metres long and around two metres wide, with the covering table weighing an estimated several tonnes. The whole structure originally rested under a mound of earth and dry stone that partially concealed the orthostats - this cairn has since largely disappeared, exposing the mineral skeleton of the dolmen to the light of day and giving it the monumental, uncluttered silhouette that characterises most French megaliths today.
