Covered arched walkway of Kerantiec
This type of monument dates from the end of the Neolithic period and was in use in the third millennium BC as a collective burial place for members of a group of farmers and stockbreeders in the country.
This monument is one of a series of eight, three in Morbihan and five in the south of Finistère. The architectural approach consisted of supporting one wall of the burial site by the other, which saves on roofing slabs, but significantly reduces the volume of the burial chamber. It is about ten metres long and oriented east-west. The eight bearing stones (southern row) are strongly inclined, the six bearing stones to the north are almost vertical. The chevet stone is in a vertical position, to the west of the structure. The entrance was from the east. The internal width of the chamber is about one metre. The stones of the monument are made of migmatite and oiled gneiss, local rocks.
