The megaliths of Carnac are located in the moors and woods around Carnac, a small town in the Morbihan department of Brittany, France. The megaliths of Carnac are the largest collection of megalithic standing stones in the world. They were erected during the Neolithic period, about 3300 years before BCE, but some of the stones are even older, probably about 4800 BCE. The more than 3000 standing stones were erected by the pre-Celtic inhabitants of Brittany. Over the centuries, many of the standing stones were removed and used for building material. It is estimated that there were once about 11.000 standing stones. The stones were erected in rows, alignments. The stones were hewn of local granite. There are three major groups of alignments: the Ménec Alignments, the Kermario Alignments and the Kerlescan Alignments. The Petit-Ménec Alignments are located in the woods near the village of Trinité-sur-Mer. There are also several tumuli scattered around Carnac, among them the tumulus of Saint-Michel and the Moustoir tumulus. There are also a number of dolmen, among them the of Er-Roc'h-Feutet Dolmen, the Kercado Dolmen and the Kerlescan Dolmen. The Manio Quadrilateral is situated near the Giant of Manio, the highest standing stone in Carnac. The megaliths of Carnacc are located near the south coast of Brittany, a peninsula south west of Normandy and north west of the Loire Valley. Nowadays, it is not allowed to walk between the alignments, they are fenced in. The Alignments of Carnac are about 1,000 years older than Stonehenge in Great Britain.
