1 –The biggest menhir in Brittany weights 30 metric tons ?
It weights much more. Menhir is a breton word : men means stone and hir means long. If you know the French Obélix, it is the stone he is carrying around. The biggest in Brittany lies in Locmariaquer (Morbihan) it used to be 21 meters (more than 65 ft) long but it is broken and lays down on the floor. It weights more than 300 metric tons.




2 – A dolmen is a circle of different stones ?
You’re wrong. A dolmen is a « stonetable » in breton language, that means upright stones that are carrying a roofstone. Dolmen are really often without roof and have misceallanous architectures : the passageway is short to long, it has one to many chambers that are round, rectangular… La Roche aux Fées (Essé, Ille et Vilaine) is a nice one. During the neolitic time, it was probably covered by earth and stones forming a barrow.



3- And what is a cromlech or a cairn ?
A cromlech is a circle of standing stones.
A cairn is a dolmen,( the stonetable I was talking about earlier), but covered by a barrow. It is hidden by an earthen mound and it looks like a small mountain. Barnenez and Gavrinis are two famous breton exemples. Here you can see the tumulus (barrow) of Dissignac close to Saint Nazaire, (Loire Atlantique).



All these buildings have been erected at several periods, some of the stones were carved with symbols. They probably have had different goals, but we don’t know for what. Some were graves, may be some others were temples but we can only guess, the stones could have religious functions, astronomical functions,... We also don’t know why our megalith builders destroyed them (menhir brisé de Locmariaquer). When Christianity begins to appear in Brittany, the stones are already used for pagan rituals, and the Church doesn’t like it. They try to christanize it and carved christian cross or others christian symbols on it.



4 – Were the Egyptian pyramides already built when our ancestors were carrying their menhirs.
Well, some of the breton buildings are much older. We know it surely since the 50’s when carbon 14 was found. And we finally discover that they are really old. The neolithic men built the megalitic buildings between – 5000 and – 2000 BC. Our Egyptian friends began their pyramids around - 3000 when our Bretons are megalith specialists. The megalith time lasted 3000 years. And the buildings done are quite different : short corridors, long corridors, square, circular chambers…



5 - Menhirs , dolmens and other megalithic buildings were built by
- a Celts
- b Druids

a – During the XVIIIth century when the “scientists” began to look at those strange constructions, they thought that the Celts built them. We know now thanks to Carbon 14 that they are much older as Celts arrived in Brittany around 500 BC.
b – Caesar wrote about the druids in their stonetemples but they just used it and did not built it.


6 – In Brittany we say that Pantagruel, and his friends let menhirs everywhere ?

May be you don’t know who is Pantagruel. he is a hero of a book from Rabelais, a French writer from the XVI th century. He is part of the French folklore. Pantagruel, a jovial fellow, is a giant with an enormous appetite, and he is good-humoured.
He is the one who left a tooth in Saint Suliac (menhir de Saint Suliac, Ille et Vilaine). He took a gravelout of his shoe and let it fall in Fort Lalatte,another one in Cap Frehel ...


7 – Others say that the fairies did it !!!
They actually did the dolmen called la Roche aux Fées, that explains its name fairyrock. Look at the work they’ve done with the stones !!!



We don’t have any written signs for this civilization and archeologists guess every time they discover something new. They think now that the settled agricultural communities, that erected the buildings, were quite organized. They probably had a leader and asked the other communities around to help them to built the monument. So the monument was a common work : it needed the help of geologists (stones were not choosen at random and were often extracted far from the place where they wanted to build the monument), engineers for the architecture, astronomists to position the building…they did not need mason as the building are done without mortar.
Some experiences have been done to try to carry the stones : in 1979 at Stonehenge, about hundred men succeded in towing a 32 metric tons stone, supported by logs and using vegetal ropes.
To extract the stones, they probably were introducing small pieces of wood in the crevices of the blocks, and swollen with water, it did fissure the block. What a job!!!


8 – The megalithic architecture was born in Brittany ?
No, it was not but the alignments of Carnac are a famous place because of his high number of stones ( about 3000 and specialists guess that they were much more, may be 10 000). You can see megaliths in many other places in the world, close to us in Corsica, in Sardinia, Malta, Majorca… but also in Asia or South America.


9 – There are just 5 to 10% menhirs left in Brittany ?
Yes, that’s right. During the XIXth century, the “learned society” wanted to study the past and were carrying out excavations. These excavations were destructives because they were just dismantling the sites and razed it after. And also for many centuries, people used the stones to build their houses, later to do the roads. They did not care of culture and inheritage at that time.


10 – Why don’t we find bones under breton stones ?

Well, because the dogs came first !!! Some of them were burial chambers and you find no bones because the soil in Brittany is acid and « eat » the bones. Flints, pottery, pearls,arrows…were found in the megalithic constructions.


11 – What were those stones used for ?
We can only guess, they must have had a religious purpose. Standing stones may be calendars, markers of territory … Dolmens or cairns were burials sites…

You’re visiting Britanny and specially the South Coast. You have to go to the Gulf of Morbihan, a small sea surrounded by peninsulas. The place is really unusual with its inland sea, an incredibly high number of islands... it's worth it.
And on the presqu'île de Rhuys, one of the peninsula that closes the Gulf, you’re close to an historical place the tumulus de Tumiac, where the legend says that Caesar did watch the naval battle between the most powerful tribe of Armor the Veneti and the Roman fleet.



Gallic War. Here we are, back in 56 before Christ when Caesar decided to conquer Brittany.
In 57, Roman already tried to dominate the peninsula. One year later, when they came back, they had to do it again. Veneti did resist and were known as good sailors. Ceasar decided to attack them, here on the South Coast. The legend said the Emperor watched the encounter from the top of this hill.



220 large sailing ships faced the Roman fleet, which was easy to move. And Romans had sickles tied to long poles that were quite useful to cut the sail down. The sailing ship could not move anymore and the soldiers just had to board the ship. And that ‘s how Caesar won this unexpected struggle… and the wind did not blow to help the Armor tribe.

That’s the legend… and now the truth about this little mound. It is on the main road that goes from Sarzeau to Port Navalo. Stop on the parking place and go on a small path that leads you to the top of the hill.



You can no more visit the underground… because of degradation…

86 m high, 20 m diameter of clay. Underneath, there is a grave (5000 before Christ).



A stone coffin 4 meters long and 2 meters wide where an important man from that time was burried. In 1853 excavations did reveal human bones which is rare in Brittany –acid soils do “eat” bones-.

The tumulus of Barnenez is at the end of the world, on a peninsula far north in Brittany… and it is a survivor in a way… because in 1954 it was almost leveled… and we are still lucky because one is left, but there used to be two or even more…



The others monuments are gone (they have been used, as usual, as stone quarry). And the one, we still can visit, almost subjected to the same fate when, what was at that time the heritage officials stopped the disapearance of the cairn.

It was already mapped in military documents during the XVIII th century, and soon in the touristic guides. But nobody was then aware of the importance of the this huge construction (72 meters long).

This neolithic tumulus (mound raised over a grave)is a stone mound of two different periods. It shelters 11 funeral chambers (dolmen or passage grave) with corridors open on the south east side.



Built between 5000 and 4000 years before Christ (the first cairn circa 4500 and the second circa 4200), the megalithic monument is a big pile of stones up to 8 meters high.

The place has been frequented for several centuries after its erection. The first mound (the one you see first) is composed of 5 chambers and is done with stones from the close surroundings. 2000 square meters, about 4000 tons of material. The archeologists think that 10 000 to 12 000 days of work were required tobuild the Barnenez cairn. That represents 10 workers working on it for 3 to 4 years.

That amount of workers could be feeded by a community of hundreds of people. Something that was not so incredible but quite possible…

The second one is an extension of the first one. 6 passage graves built in an other kind of stone (granite).



Probably because the other stone was exhausted. And they had much work because that material was more than one kilometer away. Specially because the second construction is two times more important than the first one and needed four to five times more work. Some chambers have stone walls weighting several tons and … what a job to carry them on the top of the hill.

The second cairn was used as a stone quarry and "thanks" to that mistake, we can see the inside structure of four chambers.

One is a megalithic room : big squares of stone are used as walls and roof.
Another is the symbol of the stone cupola using the technic of corbel arch done with stones.



Another mixes the two architectures.



Stone slabs were not often used : first of all, because they were heavy and hard to transport to the top of the hill… or because they were rare or because with the experience, the builders had noticed that the slabs did brake because of the heavy weight (tons of stones on them) they had to carry.

All these chambers were graves, individuals (important people even women) or collectives. And the people entered them thanks to a passage way…
This incredible monument is located on the top of a hill in a nowadays peninsula. At that time the sea level was different and under. But the place was choosen on purpose. The neolitic architects liked to admire the sea or … to be admired from far away.





Go and visit it. It is a fabulous monument… the French stonehenge…

In Brittany, south, you have a nice little sea called le golfe du Morbihan (Gulf of Morbihan) where it is really nice to cruise.
And if you like old stones and megaliths, you'll be amazed by the island of Gavrinis and its cairns.
Back a few centuries ago, when the cairn was erected, the landscape was quite different : the gulf and its 42 islands did not exist. No cruise in the sun... no 10 minutes boattrip from Larmor-Baden ... to reach the island of Gavrinis … Land replaced the sea. There was just a beautiful hill.

The island is today divided into two : one part is a private property (Council of Morbihan would have liked to purchased it but they had no money) ... Stars from Paris bought it : the farm and the dozen hectares of the island became the property of a ... Parisian .... The other tiny part is the cairn !



Back to the huge cairn ...
... It was probably part of a more important megalithic site ... Leaving the island, you will notice that the island in front of the cairn has standing stones (discovered when low tide). They are still standing! Even after billions of tides ! The builders of the Neolithic time were working really well !!!



The monument was built around 3500 BC: it is composed of a dolmen (stone table) covered by a mound of dry stone ... ie a long corridor with stone slabs that leads to a room ... it seems that the corridor is the longest in Brittany and the room is the smallest ...
And as always, my answers/questions are assumptions : no paper trail, no skeletons (Breton soil is too acidic), only ideas and imagination to understand those prehistoric people. We still can not explain these singularities ...
By cons, it seems that the corridor has been intentionally filled with stones at a time ... (the spirits did not want curious minds to destroy the place, they wanted to wait until humanity will be mature enough and concerned to "discover" this awesome vestige) ...

How did those heavy stones get there?
The assumptions are : a river had to pass near the hill Gavrinis ... stones weighing several tons have been brought by reverse flotation (the guide will explain) near the site and then rolled on logs. One of the stones of the dolmen, which is the "roof" ... corresponds to one of the broken menhir in Locmariaquer ...a huge stone over twenty meters broken into three parts ... (do not miss it !)



How do we know that our ancestors did use it as it is recovered ?
As the slab is turned towards the sky, we would never have known it... but fortunatly the cairn has been damaged... a crater at the summit was showing a part of this carved menhir … Therefore no seek of the missing piece of the table des marchants!

Another interesting detail : each stone is decorated with geometric patterns or designs ... A true team of professionnal sculptors and engravers have worked for hours to get this result: perfect lines, without corrections, with regular spaces between curves, precision work on a very hard stone (try to carve granite, you'll see!).
Presumably, the community that built the monument had artists among them !

In short, the history of the monument is exciting ... The site guides will reveal more secrets about the cairn.
You need to pay for the visit and it is only possible from April to November. Book before you go, it is often full... (same thing for accommodation, we had to drive far inland to find a place to sleep !).
For once, if crowds are passionate, there is nothing to complain about!

Have you ever read Asterix and Obelix ? If you did, you surely know the menhirs Obelix is walking around with. Well, the dolmen of La Roche aux Fées was not done by Obelix but thanks to breton fairies…



The dolmen is at about 20 km east from Rennes, under old oaks in the country of the village Essé. Once you reach Essé just follow the signs to the megalith. It is open all year long and free.
The dolmen is one of the most impressive in France : 20 meters long , 4 meters wide and you can stand inside, it was build with about 40 stones, some of them weighing more than 40 tons… Yes,the people at that time were quite strong…



A dolmen is a breton word that means table of stones, it is a chamber made with upright stones and covered with large flat capstones for the roof.…. Quite simple no… This dolmen has a long corridor, a portico nicely cut



and at the end a room. Until the 50’s the megalithic monuments were seen as building done by the Celts (they arrived in Brittany in 600 BC) but we know now thanks to the Americans that discovered the Carbon-14 that it is much older, for this one around 3500 BC.
It did not look like that during the neolitic time, because it was probably recovered by a tumulus (mound of earth and little stones). Specialists still don’t know if it was a temple or a grave (dictionnaire du patrimoine breton d’Alain Croix).
Neolitic people were really strong when you know that the stones weight more than 40 tons and that they come from an area that is 4 kms away. (foret du Theil)
Neolitic time (in Brittany from -3500 to-1800 BC) correspond to the beginning of agriculture and breeding. Thanks to the domestication of plants, a new type of social organisation appears with a specialization of men and work. They begin to build those monuments. But to build them they need specialized workers : “ geologists ” that choosed the type of stones, “ architects ” that think and build the construction and "drivers" to transport the stones – we guess that they were using woodlogs to rool the stones - , and "astronomists" that decide in which direction the corridor will be.




The building is orientated Northwest-South South East but it is not fate. No, it is a solstice alignment. You should go there on a 21 december and you’ll see the sunrays penetrating the building just in its center. You said they were wearing beast skins…
But may be we’re wrong and the fairies did it. That explains its name (Roche aux Fées = fairies rock) , the legend says that the fairies carried the stones from Le Theil. They let some fall around (at Retiers la Pierre de Richebourg or at Janzé la Pierre des Fées). I ll tell you the legend another day…

To sum up, you have to visit the dolmen for three reasons :
- to quench your curiosity
- to do the same thing that neolitic men were doing on december 21st
- to be sure of your lover. Don’t trust meetic, and test your love at la Roche aux Fées (also called lovers’oracle). Take your love on a full moonnight. Count the stones. If you find the same number, go on and marry him or her. If you don’t… recount them…
Last thing : take care of the building. I want my grand,grand grandgrand children to see it...
Leaving the place you can taste nice local products, see you on the next post
