The Ancient Cairn de Barnénez at Plouezoc'h

The Ancient Cairn de Barnénez at Plouezoc'h

Right at the top of Finistère, at the top of a steep peninsula overlooking Morlaix Bay, sits the Cairn de Barnenez, Europe's largest megalithic burial chamber!

The Cairn de Barnenez is classed as a National Monument, and rightly so. Situated just outside Morlaix, this is the largest megalithic burial chamber in all of Europe and is said to be the second oldest monument in the world, only a little younger than the Tower of Jericho.

Dominating the sea, the Cairn consists of a fantastic 75-metre corridor that is 28 metres wide and it dates from 5000 BC. This makes the Cairn about 2000 years older than the Egyptian Pyramids. Overlooked for a long time, this astonishing mass of stones includes 11 standing stones and was brought to light in 1955 during works for a quarry. 

As one of the most ancient structures on earth, it certainly deserves its name from French writer and politician André Malraux, who called it "the Prehistoric Parthenon".
