Overview
The Kerbourg menhir, also called the Pierre Blanche de Kerbourg or the Pierre de Trémélu, is a standing stone of white quartz, 2.10 m high, in the commune of Saint-Lyphard, in the département of Loire-Atlantique, France. The Atlas catalogue gives a typological estimate of 2800 to 1800 BCE.
The site was excavated in October 1896 by Henri Quilgars, whose findings suggest that the stone may have been erected or re-erected in the Roman period.

The menhir of the Pierre-Blanche is a block of white quartz 2.10 m high. Until the early twentieth century a large granite slab known as the menhir Tombé-du-Loin was visible in its immediate vicinity.

The site was excavated in October 1896 by Henri Quilgars. The ground on which the menhir was set up is full of Gallo-Roman roof-tile debris (tegulae), and the base of the menhir itself was wedged with this kind of material, which suggests that it was erected or re-erected at that time.
On the granite slab Quilgars recognised two distinct types of cupules. The first are hemispherical, with a diameter of about 3 cm, and may have been made by abrasion with a stone. The second are conical and were evidently dug with a metal tool. Flint flakes were found beneath the slab.

Pitre de Lisle mentions the two stones together under the name menhirs de la Pierre-Blanche. According to Quilgars, the two megaliths are independent and date from different periods: the stone called Tombé-du-Loin could have been a Neolithic monument, while the Pierre Blanche would date from the Roman period.
Tradition and region
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.
