Archaeological site unearthed in 2020 by villagers who, while clearing a low wall, realized that they were on a vast terraced wall 60 meters long. These dry stone walls are spread out over a height of 40 meters on the hillside. The origin, probably Celtic, remains uncertain and the function very mysterious. Military? Agricultural? Religious? Druidic? A bit of everything at once? This complex is part of a very pleasant natural site on the banks of the Divatte River. Numerous picnic tables, toilets and drinking water.

Actually, it's more of an allée couverte—but I don't even want to know what Komoot translates into. Fifty meters further on, there's a second collapsed dolmen.

Impressive dimensions. It is hidden away in a dead end street and absolutely worth seeing. In the immediate vicinity there is another dolmen, a pretty old mill and great little houses with thatched roofs.
