Le Rocher tumulus, Kernours

Featuring a large tumulus and a large number of small graves, the Kernours site is close to Auray river. 

This tumulus is an “elbow” shaped (or “right-angled”) burial place. Dating back to the end of the fourth millennium BC, its architectural forms are specific to the southern coast of Brittany. There are seven such tumuli between the Loire and Blavet estuaries. Only two of these burial places still have their tumulus in place: Le Goërem in Gâvres and Le Rocher tumulus in Le Bono, the latter being particularly well preserved. The monument is about 20m in diameter and 4m high. Its internal architecture consists of alternating megalithic pillars and dressed stone walls. The ceiling is covered with megalithic slabs. The corridor measures around 12m up to the bend, which opens onto a burial chamber about 8m long.

On five of its pillars, Le Rocher tumulus has engravings which are quite typical for elbow-shaped graves. (Les Pierres Plates in Locmariaquer, Le Luffang in Crac’h, Le Goërem in Gâvres, etc.).

During the Iron Age (around 800 BC), smaller structures – six circular graves with chests – appeared around this monument. 

The site is a Sensitive Natural Area and the property of the Morbihan département. It is run by Le Bono town hall and open all year.
