This gallery grave dates back to the Neolithic Era, between 3000 and 2500 BC. Attested traces of human occupation from the Iron Age at the Guildo castle testify to the oldness of the presence of men on this part of the coast.
This gallery grave is an old collective grave, almost 13m long, 1.10m wide and 0.90m high.
A hundred men and a good organisation were necessary to build it.
