Site archéologique du dolmen des Aguals ou de la Combe de l'Ours (également sur commune de Montbrun), located in Gréalou (Département 46), is a historic monument. The monument is currently closed to visitors.
Standing on the Quercy limestone plateaux, the Aguals dolmen reveals the megalithic soul of the Lot: a Neolithic burial chamber of remarkable integrity, a stone sentinel that has watched over the Combe de l'Ours for five millennia.
On the limestone plateau of the Causses du Quercy, on the border between the communes of Gréalou and Montbrun, the Aguals dolmen emerges from the garrigue like a message left by the first builders of the Lot. This collective burial site, built at the crossroads of the Neolithic and Chalcolithic periods, is one of those rare monuments that forces visitors to reconsider their own notion of time. Far from the tourist hustle and bustle of the great Breton megalithic sites, it offers a silent communion with one of the oldest expressions of humanity. What sets the Aguals dolmen apart from other megalithic sites in the Quercy region is first and foremost the quality of its conservation. Where many of its regional contemporaries can now only be discerned through a few collapsed orthostats, this one retains exceptional architectural legibility, enabling the structural logic of these rediscovered sky burial chambers to be understood at a glance. It is precisely this integrity that led to the site being listed as a Historic Monument. The experience of visiting the site is one of total immersion in the caussenard landscape. The paths that lead there cross expanses of lapiaz, dry grassland and centuries-old juniper trees, providing a gradual approach that prepares the mind for the encounter. The Combe de l'Ours, whose name the dolmen also bears, adds a geographical and legendary dimension to the site, this steep-sided valley having fed the local imagination for generations. The site is equally suited to amateur archaeologists, curious families and photographers in search of timeless compositions. The horizontality of the great limestone slabs contrasts with the verticality of the Quercy sky, particularly at the end of the day when the low-angled light tints the stone ochre and honey, giving the site a natural and sovereign photogenic quality. Listed as a Historic Monument by two successive decrees in 2001 and 2002, the Aguals dolmen now enjoys institutional recognition commensurate with its heritage value. It is part of a network of megaliths in the Quercy region, making the Lot one of France's richest departments in terms of recent prehistoric remains.
The Aguals dolmen belongs to the architectural type of corridor dolmens or simple burial chambers characteristic of the megalithism of the Causses du Quercy, distinct in its forms from the Breton alignments or the dolmens of Anjou. Its structure is based on the universal principle of the trilithon: orthostats of local limestone planted vertically in the ground and topped by one or more horizontal cover slabs forming the roof of the chamber. This dry assembly system, with no binding agents, relies solely on the balance of the masses and the deep anchoring of the uprights in the Caussen soil. The Jurassic limestone of the Causses, the material of choice for the megalithic builders of the Quercy region, is characterised by its ability to be cut into relatively regular slabs along its natural stratification planes. This property of the local geological substratum partly explains the density and quality of the megaliths in this region: the raw material abounded right on the plateau. The colours of the stone range from creamy white to bluish grey, depending on the degree of exposure to the elements, and the surfaces are now colonised by golden and silvery lichens that make the monument part of the causse's chromatic palette. The exceptional architectural quality of the Aguals dolmen, highlighted by the Mérimée database, is due to the fact that the structure as a whole has been well preserved: the orthostats are still in place, the roof slab has not undergone any major displacement, and the chamber retains a spatial legibility that makes it possible to grasp the interior volume as it was designed by its builders. This integrity makes it a textbook case for the study of megalithism in the Causse region, and gives it both educational and aesthetic value.
