Le Dolmen du Couperon The site has been badly excavated and restored, first in 1868 and again in 1919. An interesting feature of the monument is the porthole slab at the entrance.
This Late Neolithic gallery grave (or allée couverte) was built around 5,000 years ago (3250-2250 BC). It consists of a rectangular chamber set within an enclosure of upright stones, which may originally have formed the edge of a long low mound that covered the monument.
