Origin and history

The two gallery dolmens with tumulus remains, located in Crach in Morbihan (British), date from Neolithic. These funeral monuments, typical of this period, bear witness to the architectural and ritual practices of local prehistoric societies. Their presence in Parc-Guéren, with an official ranking in 1926, underscores their heritage importance and preservation.

In the Neolithic, Brittany was marked by an agropastoral society where dolmens served as collective burials. These megalithic structures reflect a complex community organization, centred around the memory of ancestors and the management of territories. Their location in Crach, near Kerorang, illustrates the sustainable settlement of populations in this coastal region rich in natural resources.

The classification of the dolmens by decree of 12 May 1926 allowed their protection as Historical Monuments. This official recognition underlines their archaeological value and their role in understanding Breton Neolithic cultures. Their present state, with remains of tumulus, offers valuable clues about the construction techniques and beliefs of the time.
