The Allée Couverte du Grah Niol (hill or mountain of the sun) is located north of the church shortly after school.
This dolmen has a side chamber on the left.
Engravings are visible on the same right and left supports, the one on the right facing the side chamber, and the one at the bottom on the right with a silhouette called the Goddess.
The last cover slab shows the outline of a hilted ax.
Outside, we can vaguely find the trace of the circular tumulus.
The menhir at the entrance is believed to have been brought back.
Free access all year round.
