Cairn II
A large trapezoidal mass leans against the south-eastern side of cairn I. It has a subpentagonal shape, about 40x30x30m, which almost doubles the initial volume.
Two main sides are visible, in the north-west (belonging to Cairn I) and in the east (severely damaged by the bunker built as part of the "Wall of the Atlantic").
In the middle of the eastern side, there was probably a dolmen passage. Its chamber is almost central, in the heart of the monument.
