Overview
The Pierre Longue, also known as the Pierre longue or the menhir de Saint-Michel, is a menhir at Batz-sur-Mer in the département of Loire-Atlantique, France. The catalogue gives a typological estimate of 2800 to 1800 BCE for its date.
The stone measures 2,40 m in height, 1,80 m in width and 0,40 m in thickness. It was brought down by a storm in 1895 and had still not been raised in June 1900.

This assertion seems rather improbable, since the stone is hardly visible from the open sea.

The menhir is a broad, thin slab, 2,40 m high, 1,80 m wide and 0,40 m thick. It stands on a rock called the Tombeau du Diable, which itself covers the Trou du Diable.
Several authors state that the stone once served as a sea-mark for coastal navigation. This assertion seems rather improbable, since the stone is hardly visible from the open sea.

Local tradition holds that the rock beneath the menhir is the one on which Saint-Michel confronted and defeated the Devil.
According to legend, a treasure was buried at the foot of the stone by a child or a salt-worker (paludier), who had stolen it from the cave of the Korrigans on the wild coast of Le Pouliguen.
Until late in the nineteenth century, the young women of the town came to consult the menhir around 15 August. By dancing in rings and singing around the Pierre Longue they asked for their plans to be fulfilled, marriage above all. If one of the dancers unluckily touched the stone, she would not marry within the year.

A menhir is a large upright stone placed by humans. The word comes from the Breton maen and hir, "long stone"; 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.

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.

Dated moments in the story
- 1895
Abattu par une tempête en 1895, il n'était toujours pas relevé en juin 1900. Bien que plusieurs auteurs mentionnent qu'il servait jadis d'amer pour la navigation côtière, cette assertion semble assez improbable car de fait il est peu visible du large.

- Tradition
Le menhir se dresse sur un rocher appelé le Tombeau du Diable, qui lui-même recouvre le Trou du Diable.
Le menhir se dresse sur un rocher appelé le Tombeau du Diable, qui lui-même recouvre le Trou du Diable. Le rocher serait celui où Saint-Michel affronta et vainquit le Diable. Selon la légende, un trésor a été enterré à son pied par un enfant ou un paludier après l'avoir dérobé dans la grotte des Korrigans, sur la côte sauvage du Pouliguen. Jusque dans les années 1870-80, la tradition voulait que les jeunes filles du bourg viennent consulter ce menhir aux environs au 15 août. Par des rondes et des chants autour de la pierre Longue, elles demandaient la réalisation de leurs projets, notamment le mariage. Si par malheur une des danseuses touchait la pierre, elle ne se marierait pas dans l'année.
