Origin and history

The three tumulus of Keranhouët, located in the commune of Saint-Gildas in the Côtes-d'Armor, date from the Bronze Age. These funeral monuments, typical of this period, are collective or individual burials, often associated with rites and beliefs related to death and the afterlife. Their presence illustrates the importance of funeral practices in Breton protohistoric societies, where tumulus were used to mark the landscape and honour the deceased.

The Bronze Age in Brittany, between 2200 and 800 B.C., is a period marked by the development of agriculture, livestock and handicrafts, including bronze metallurgy. The tumulus, like those of Keranhouët, were often erected on strategic or symbolic sites, reflecting a complex social organization and a spirituality rooted in the territory. These monuments, although discreetly integrated into the landscape, played a central role in the collective memory of local communities.

Keranhouët's tumulus were registered as Historical Monuments by order of 31 August 1964. This official protection recognizes their archaeological and heritage value, while ensuring their preservation for future generations. Their location, although documented in the Merimée base with an accuracy deemed fair (note of 5/10), remains a valuable testimony of the ancient human occupations in Brittany.

Today, these tumulus are key elements of the Breton archaeological heritage. Their study allows researchers to better understand the lifestyles, beliefs and construction techniques of Bronze Age populations. Although their access and visibility may be limited, they are an invaluable legacy for local and regional history.
