The visit
An opportunity to discover the history of the site and the latest archaeological hypotheses.
The Great Broken Menhir, an enormous 21-metre block of granite weighing almost 300 tonnes, the Er Grah tumulus and the Table des Marchands dolmen with its magnificent engravings, provide exceptional evidence of the funerary rites practised in Brittany 4500 BC.
