Dolmen et cromlech de Sénevaut, located in Ciron (Indre), is a historic monument. The monument is currently closed to visitors.
In the heart of the Brenne, the Sénevaut dolmen and cromlech form an exceptional Neolithic megalithic complex: a circle of standing stones encircling a burial chamber, a striking vestige of 5,000 years of history.

Just a few kilometres from the village of Ciron, in the Indre department, the Sénevaut megalithic site is one of the most eloquent testimonies to the presence of humans in the Centre-Val de Loire region at the dawn of historic times. The combination of a dolmen and a cromlech - the term used to describe a circle or line of menhirs - gives this site an architectural richness that is rare in the region, where megalithic monuments of this complexity are few and far between. The dolmen, the centrepiece of the system, is what archaeologists call a burial chamber: several orthostats - vertical slabs of sandstone or limestone - support a massive covering table, forming an interior space once used for collective burial deposits. In the immediate vicinity, the cromlech extends its circle of standing stones across the bare grass, creating a sacred geography whose function - ritual, astronomical or memorial - continues to fuel the hypotheses of researchers. To visit Sénevaut is to allow yourself to be swept away by silence and time. The stones, patinated by the centuries and covered in golden lichen, speak of a world before writing, of a Neolithic society that had already mastered the collective organisation of work, knowledge of the landscape and a sense of the sacred. The low-angled light of morning or evening enhances the relief of the blocks and reveals the deliberate layout of the site, whose orientation is no doubt no accident. The natural setting enhances the experience: the Brenne region and its surroundings, a land of ponds and hedged farmland, offer an unspoilt environment conducive to contemplation. Fans of archaeological walks will find the circuit around Ciron a complete programme, combining the megalithic heritage and natural landscapes characteristic of the south of the Indre. Listed as a historic monument since 1889, Sénevaut's protection bears witness to the early interest shown in these stone legacies by 19th-century scholars.
The Sénevaut dolmen displays the classic morphology of Neolithic collective burials in central France: a funerary chamber with an approximately rectangular plan, made up of several vertical slabs of local limestone or sandstone, topped by a covering table whose mass - estimated at between two and five tonnes, depending on the size of the monument - rests on the lateral and frontal orthostats. Access to the chamber was probably via an entrance corridor, now partially collapsed, oriented along a solar axis favouring east or west at the equinoxes, as comparisons with similar dolmens in Berry and neighbouring Touraine suggest. The associated cromlech forms a circle or arc of smaller menhirs, planted in the ground at regular intervals around or near the dolmen. This feature, which is relatively rare in the Centre-Val de Loire region, is reminiscent of the large ceremonial ensembles in Brittany or the British Isles, albeit on a smaller scale. The diameter of the circle of stones, typically between ten and twenty-five metres for this type of monument, organises a procession or ritual gathering area around the central sepulchre. The stones, of varying heights, are carved from locally available materials, giving the site a homogenous colour scheme of beige and grey, with a patina of lichen and weathering. Despite the passage of centuries and the occasional re-use of blocks by local farmers, the whole structure retains sufficient architectural legibility to allow us to perceive the spatial intention of its builders.
