Dolmen de Mané Rethual - Locmariaquer (France)

This dolmen is situated about 300m from the Table des Marchand. It is also known as Mané Rutual or Men Er Rutual and dated at about 3800 BC. With its length of 20m it is the longest passage grave in Brittany (passage 9,50m, prechamber 6,50m, main chamber 5m).

Most of the stones consist of local granit but the broken topstone is from orthogneiss from Auray (10 km away).

In former times the dolmen was covered by stones as a tumulus and by sand and plants, too.
