Allée couverte du Blanc
MonumentHidden Treasure
A Neolithic vestige buried in the Périgord Noir, the covered alleyway at Le Blanc in Nojals-et-Clotte reveals the secrets of a building people who disappeared over 5,000 years ago, frozen in the stone and silence of the Dordogne hills.
History
In the heart of the Périgord Noir, in the discreet commune of Nojals-et-Clotte, stands one of the oldest testimonies to human presence in the Dordogne: the covered alleyway of Le Blanc. This megalithic monument, listed as a Monument Historique since 1971, belongs to the family of collective burial sites that Neolithic builders erected with disturbing precision and intention, several millennia before our era. Unlike the isolated dolmens that dot the Périgord landscape, the covered alley is distinguished by its elongated structure, a veritable stone corridor leading to a burial chamber. Here at Nojals-et-Clotte, the slabs of local limestone - an abundant material in this karstic terroir - have survived the millennia without failing, offering the attentive visitor a lesson in primitive architecture of rare intensity. The visit is above all a sensory and contemplative experience. Getting up close to these massive orthostats, feeling the weight of time inscribed on each eroded surface, imagining the funeral processions that animated this sacred place: this is the promise of this little-visited site, spared the crowds that flock to the more famous decorated caves. It is precisely this discretion that makes it such a special place for lovers of authentic heritage. The natural setting enhances the atmosphere of the site. The gentle, wooded hills of the Bergerac region envelop this vestige in dense vegetation where downy oaks and coppice create a penumbra conducive to historical meditation. The filtered light of late afternoon reveals with particular acuity the work of cutting and assembling these Neolithic men who, without metal or wheels, moved and erected blocks weighing several tonnes.
Architecture
The covered alleyway at Le Blanc is typical of the elongated collective burials of the Final Neolithic of south-western France. Its structure consists of a series of orthostats - large slabs standing vertically - forming the side walls of a corridor oriented on an east-west axis, an orientation common to many funerary monuments of this period, possibly linked to solar cycles. Horizontal cover slabs, known as tables, rest on these uprights to close off the burial chamber. The materials used are exclusively local: Périgord limestone, taken from the karstic outcrops that abound in this part of the Bergerac region, makes up the entire construction. This chalky limestone, relatively soft when quarried but hardened by exposure, was worked using stone and wood tools. The largest blocks probably weighed between two and four tonnes, testifying to the considerable collective effort required to transport and install them. Initially, the ensemble would have been covered by a dry stone cairn or earth mound, creating a visible tumulus in the landscape and signalling the presence of a sacred space to the surrounding communities. Erosion over the millennia has largely reduced this mound, leaving the emerging lithic structures in their austere nakedness - this contemporary stripping down gives the monument a visual power that its designers may not have envisaged.
