This impressive Neolithic complex features three large megaliths that have become symbols of Brittany: the Broken Menhir of Er Grah, the Table des Marchands and the Tumulus d'Er Grah, all of which date back to between 4700 and 3800 BC. The Broken Menhir is a vast broken granite block and the largest of its kind known in Europe, measuring over 20m in length with a weight of 330 tonnes. The Tumulus d’Er Grah and the Table des Marchands provide an exceptional insight into the ancient funeral rites practised in Brittany at the time. A gallery leads down to the underground burial chamber and some of the walls have been engraved with hieroglyphics. A tour of the site is an ideal introduction to the architecture and civilisation of the megalithic age, all in a stunning natural environment with superb views of the Golfe du Morbihan.
The site is accessible to visitors with reduced mobility and there are guide booklets available in French, German, English, Italian, Spanish, Dutch, Czech and Breton. Guided tours are available in French all year round; for those in other languages please contact us.
