Visit the Cairn of Barnenez

The Barnenez cairn is one of the first traces of buildings made in durable materials in Europe

Situated on the Kernéléhén peninsula in the Finistère-Nord region, the Barnenez Cairn is a truly exceptional megalithic site. This large tumulus is, in fact, composed of two adjacent cairns (stone pyramids), dating from 4500 to 3500 BC, known as the “Prehistoric Parthenon”. This vast construction made entirely from carefully piled stones comprises eleven funeral chambers connected by galleries.

The Barnenez site is a gem of the Neolithic age when mankind began to settle, develop livestock farming and agriculture, pottery, weaving and other civilised crafts.
