Barnenez

The Cairn of Barnenez is a Neolithic monument located near Plouezoc'h, on the Kernéléhen peninsula in northern Finistère, Brittany, France [1]. Radiocarbon dates indicate that the first phase of the monument was erected between 4850 and 4250 BC, and the second phase between 4450 and 4000 BC [1]. The Barnenez cairn is 72 m long, up to 25 m wide, and over 8 m high [1]. It is built of 13,000 to 14,000 tons of stone [1]. It contains 11 chambers entered by separate passages [1]. The 11 chambers of the Barnenez cairn are of the type known as Dolmen à couloir in French archaeological terminology [1]. Engraved symbols occur in several of the chambers and passages [1].
