Trois tumulus de Keranhouët, located in Saint-Gildas (Département 22), is a historic monument. The monument is currently closed to visitors.
A trio of Bronze Age tumuli nestling in the Breton moors of Saint-Gildas, these burial mounds reveal the burial rites of a civilisation that disappeared over 3,000 years ago.
In the heart of inland Brittany, in the commune of Saint-Gildas in the Côtes-d'Armor, the three Keranhouët burial mounds form a remarkable Bronze Age funerary complex. These monuments of earth and stone, erected by prehistoric populations between 2000 and 800 BC, bear witness to an elaborate social organisation and a conception of the world in which death called for highly sophisticated collective rites. Their grouping in trio - rare in itself - suggests an aristocratic or clan necropolis, reserved for exceptional individuals within their community. What makes Keranhouët particularly precious is the remarkable preservation of these mounds in an authentic Breton landscape. Unlike many megalithic sites that have been levelled by centuries of agriculture, these three mounds retain their bulging silhouettes, legible and impressive in the sparse vegetation of the moors. Brittany, a land of granite and mystery, is home to one of the highest concentrations of prehistoric funerary monuments in Western Europe, and Keranhouët is one of its little-known but significant landmarks. Keranhouët is one of the lesser-known but significant landmarks of this period. The visit is aimed at both archaeology enthusiasts and walkers looking for an authentic connection with the depths of time. You can walk freely around the mounds, whose dimensions - several metres high and with diameters that can exceed twenty metres - impress with their silent mass. The site invites contemplation: no barriers, no artificial scenography, just the earth accumulated by human hands three millennia ago, and the changing light of Brittany. The surrounding environment reinforces the timeless atmosphere. The moors and hedgerows of this part of the Côtes-d'Armor region offer a silence that is disturbed only by birds and the wind. The three burial mounds seem to watch over a land that they marked long before the first menhir of Carnac was erected - or at least for as long - making Keranhouët a site that speaks directly to the imagination as much as to reason.
The Keranhouët burial mounds belong to the type of central chamber mounds characteristic of the Armorican Bronze Age. Each is a sub-circular mound, probably between fifteen and twenty-five metres in diameter at the base, with a preserved height of between one and four metres, depending on the state of preservation. This asymmetry between neighbouring mounds is common in grouped necropolises: it generally reflects the social hierarchy of the individuals buried, with the largest mound reserved for the highest-ranking person. Construction follows a concentric stacking logic: around a central burial chamber - often a box of slabs made of granite or local schist, materials that are abundant in this part of the Côtes-d'Armor - the builders accumulated layers of clay soil, gravel and sometimes wedging stones arranged in a ring. This protective envelope served not only to mark the grave in the landscape, but also to consolidate the chamber against water infiltration and collapse. Some Breton burial mounds from this period also feature a crown of stones at their base, acting as a border and perhaps a ritual marker. Today, the vegetation - bracken, gorse, moss and heath grasses - completely covers the three mounds, giving them the appearance of natural hills that only a trained eye can recognise as human works. It is precisely this integration into the landscape that constitutes their main architectural charm: at Keranhouët, architecture cannot be dissociated from nature, and the monument only fully exists in its dialogue with the Breton sky and the Armorican earth.
