The Er Grah tumulus

A site of extraordinary proportions

First of all, archaeologists discovered that this monument had not been built all at once, but over several centuries. Starting out as a small cairn, the architecture was stretched to the north and south to reach a length of almost 140 metres, forming this distinctive trapezoidal structure of stone and earth: a tumulus.

Objects that take us on a journey

It's not just its length that makes you dizzy, but also the provenance of the funerary objects found in the vault during archaeological digs in the early 20th century! Unusually coloured axes and pendants from the Italian Alps and the Iberian Peninsula respectively highlight the existence of a Europe-wide circulation of prestige goods at the end of prehistoric times. How were these trade networks organised?
