The menhir has the form of a four-sided pyramid whose faces measure 1.60 m, 0.80 m, 1.80 m and 1.70 m at the base. It is 5.10 m high and leans slightly towards the south. The stone has been Christianised.
According to one legend, the devil was carrying a gigantic stone under each arm and lost the first here and the second at Dol, where it became the menhir of Champ-Dolent.

About this kind of monument
Breton and French menhirs
A menhir is a large upright stone placed by humans. The word comes from the Breton maen and hir, "long stone", and entered archaeology through French antiquarians in the eighteenth and nineteenth centuries; in modern Breton the word for such a stone is peulvan. Menhirs are most numerous in Western Europe, with about 1,200 in north-western France alone, and Brittany stands out for both the density of monuments and the variety of types.
The largest known menhir is the Grand Menhir Brisé at Locmariaquer. It once stood nearly 20.6 metres high, and now lies fractured in four pieces; whole, it would have weighed some 330 tonnes. Stones in the Carnac area were hewn from local granite by the pre-Celtic people of Brittany. At Carnac more than 3,000 prehistoric standing stones form the largest such collection in the world, arranged in groups of alignments that stretch for four kilometres. The stones were erected at some point in the Neolithic, probably around 3300 BCE, with some perhaps as early as 4500 BCE. Elsewhere, the Cham des Bondons in the Cévennes is the second largest concentration in France, and a menhir 4.5 metres tall stands against Le Mans Cathedral, moved there in 1778 when its dolmen was destroyed.
Dating a menhir is difficult, because standing stones are usually hard to date and were put up in many different periods.
Folklore: a Christian legend held that the stones of Carnac were pagan soldiers who had pursued Pope Cornelius and were turned to stone by him. Modern beliefs link the stones with Roman and Christian occupation, even though they date from 4500 to 3300 BCE.
When visiting, look at how the stones taper towards the top and at how the alignments run across the slope.
