Carnac stones

There are three major groups of stone rowsMénec, Kermario and Kerlescan. They may have once formed a single group but have been split up as stones were removed for other purposes. Together they trace a contour line, around 20 meters above sea level. The standing stones are made of weathered granite from local outcroppings that once extensively covered the area. Ménec alignments Eleven converging rows of menhirs stretching for . There are what Alexander Thom considered to be the remains of stone circles at either end. According to the tourist office there is a "cromlech containing 71 stone blocks" at the western end and a very ruined cromlech at the eastern end. The largest stones, around high, are at the wider, western end; the stones then become as small as high along the length of the alignment before growing in height again toward the extreme eastern end. Kermario alignment This fan-like layout recurs a little further along to the east in the Kermario (House of the Dead) alignment. It consists of 1029 stones in ten columns, about in length. A stone circle to the east end, where the stones are shorter, was revealed by aerial photography. Kerlescan alignments A smaller group of 555 stones, further to the east of the other two sites. It is composed of 13 lines with a total length of about , ranging in height from to .

There are several tumuli, mounds of earth built up over a grave. In this area, they generally feature a passage leading to a central chamber which once held neolithic artifacts. Three exceptionally large burial mounds are known from the Carnac and Morbihan area, dating from the mid-5th millennium BC and known collectively as 'Carnacéen tumuli': Saint-Michel, Tumiac and Mané-er-Hroëk. Each of these tumuli contained a megalithic burial chamber, containing the burial of only one individual, along with numerous large polished stone axeheads, stone arm-rings, and jewellery made from callaïs (variscite and turquoise). Scientific analyses have shown that many of the axeheads are made of jade from the Italian Alps, whilst the callaïs was imported from south-western Iberia. Archaeological evidence indicates that the callaïs was brought from Iberia by boat, across the Bay of Biscay, rather than along the coast or overland. The extraordinary nature of these burials, the scale of the tumuli, the logistics and effort involved, all indicate that these were the burials of extremely important elite individuals, that some researchers have described as "divine kings". The large-scale effort and organisation involved in the construction of megalithic monuments, such as the Grand Menhir of Er Grah, further suggests the existence of rulers or kings in the Carnac and Morbihan region. A similar situation has been described for the later megalithic culture in Ireland, which shows some close similarities to the megalithic culture in Brittany. Based on archaeological, DNA and ethnographic evidence it has been suggested that an elite male buried in the Newgrange passage grave, c. 3200 BC, may have been a "god-king" and part of a "dynastic elite". Similarities have also been noted with the Michelsberg culture in northeastern France and Germany (c. 4200 BC), which featured large tumulus burials within fortified settlements and the use of Alpine jade axes, all associated with the emergence of "high-ranking elites". Engravings on megalithic monuments in Carnac also feature numerous depictions of objects interpreted as symbols of authority and power, such as curved throwing weapons, axes and sceptres. in the distance The Carnacéen tumuli were contemporary with the rich burials of the Varna culture in Bulgaria (c. 4500 BC), which contained more gold than all excavated sites from the rest of the world combined in the 5th millennium BC. The Varna burials attest to the existence of powerful elites in southeastern Europe at the same time as they appear in Carnac. Grave 43 of the Varna necropolis, which contained a single male buried with a sceptre and numerous gold ornaments, also contained an Alpine jade axehead. Saint-Michel The tumulus of Saint-Michel was constructed between 5000 BCE and 3400 BCE. At its base it is , and is high. It required of stone and earth. Its function was a tomb for the members of the ruling class. It contained various funerary objects, such as 15 stone chests, large jade axes, pottery, and callaïs jewellery, most of which are currently held by the Museum of Prehistory of Carnac. It was excavated in 1862 by René Galles with a series of vertical pits, digging down . Le Rouzic also excavated it between 1900 and 1907, discovering the tomb and the stone chests. A chapel was built on top in 1663 and was rebuilt in 1813, before being destroyed in 1923. The current building is an identical reconstruction of the 1663 chapel, built in 1926. Tumiac The tumulus of Tumiac is located in Arzon, in the Rhuys peninsula, south of the Gulf of Morbihan. It is also known as 'Caesar's mound' because, according to local legend, it served as an observatory for Julius Caesar during his war against the Veneti in 56 BC. The site was excavated in 1853. The crater visible at the top of the tumulus corresponds to the vertical hole made at the time for its exploration. It was the subject of new excavations and work in 1934, which brought to light several secondary burials. The tumulus, circular/elliptical in shape, is made up of layers of clay. It measures 50 m in diameter and 15 m in height. It contains a central rectangular burial chamber 4.40 m long, 2.40 m wide and 1.75 m high. This chamber is made up of three monolithic supports and is covered with a quartz slab 4.80 m long. It had a wooden floor and two engraved side slabs. The funerary chamber contained rich furniture consisting of 11 jadeite axes, 26 fibrolite axes and 249 callaïs beads. These objects are kept in the Archaeological Museum of Vannes. According to carbon-14 dating, the tumulus of Tumiac was erected between 4790 and 4530 BC. The tumulus of Tumiac has been classified as a historical monument since 1923. Mané-er-Hroëk The Tumulus of Mané-er-Hroëk (also known as the Tumulus du Ruyk) is located in Locmariaquer, Morbihan, immediately west of the hamlet of Er-Hroueg and about 1 km northeast of the Pierres Plates dolmen. The tumulus comprises a rectangular burial vault of about 5 m by 3 m, covered with two roofing slabs, supporting a mound about 100 m long and 60 m wide. The tumulus rises to approximately 15 m above sea level, or almost 8 m above the natural ground. The current entrance, with a staircase, is a modern addition. An engraved stele, found broken into three pieces, stands next to the entrance. The tumulus was excavated in 1863 by the Polymathic Society of Morbihan. These excavations led to the discovery of the vault and stele and brought to light 106 precious stone axes (the largest of which measures 46 cm), 49 callaïs beads and 9 callaïs pendants. These objects were subsequently deposited in the Archeological Museum of Vannes. The tumulus has been classified as a historical monument since 1889. Moustoir Also known as Er Mané, it is a chamber tomb long, wide, and high. It has a dolmen at the west end, and two tombs at the east end. A small menhir, approximately high, is nearby. ==Grave goods==

There are several dolmens scattered around the area. These dolmens are generally considered to have been tombs; however, the acidic soil of Brittany has eroded away the bones. They were constructed with several large stones supporting a capstone, then buried under a mound of earth. In many cases, the mound is no longer present, sometimes due to archeological excavation, and only the large stones remain, in various states of ruin. ''Er-Roc'h-Feutet'' North, near the Chapelle de La Madeleine. Has a completely covered roof. La Madeleine A large dolmen measuring , with a long broken capstone. Kermarquer On a small hill, has two separate chambers. Mané-Kerioned (Pixies' mound or Grotte de Grionnec ==Other formations==

There are some individual menhirs and at least one other formation which do not fit into the above categories. Manio quadrilateral An arrangement of stones to form the perimeter of a large rectangle. Originally a "tertre tumulus" with a central mound, it is long, and aligned to east of northeast. The quadrilateral is wide to the east, but only wide at the west. Manio giant Near the quadrilateral is a single massive menhir, now known as the "Giant". Over tall, it was re-erected around 1900 by Zacharie Le Rouzic, ==Excavation and analysis==

From the 1720s increasing interest was shown in these features. In 1796, for example, La Tour d'Auvergne attributed them to druidic gatherings. Ronalds created the first accurate drawings of many of them with his patented perspective tracing instrument, which were printed in a book Sketches at Carnac (Brittany) in 1834. Miln and Le Rouzic The first extensive excavation was performed in the 1860s by Scottish antiquary James Miln (1819–1881), who reported that by then fewer than 700 of the 3,000 stones were still standing. Towards 1875, Miln engaged a local boy, Zacharie Le Rouzic (1864–1939), as his assistant, and Zacharie learnt archaeology on the job. After Miln's death, he left the results of his excavations to the town of Carnac, and the James Miln Museum was established there by his brother Robert to house the artifacts. Zacharie became the director of the Museum and, although self-taught, became an internationally recognised expert on megaliths in the region. He too left the results of his work to the town, and the museum is now named Le Musée de Préhistoire James Miln – Zacharie le Rouzic. Other theories In 1887, H. de Cleuziou argued for a connection between the rows of stones and the directions of sunsets at the solstices. Thom's megalithic yard has been challenged. There are also general theories on the use of the stones as astronomical observatories, as has been claimed for Stonehenge. According to one such theory, the massive menhir at nearby Locmariaquer was linked to the alignments for such a purpose. ==Management==

The Musée de Préhistoire James Miln – Zacharie le Rouzic is at the centre of conserving and displaying the artefacts from the area. As with the megalithic structure of Stonehenge in England, management of the stones can be controversial. Since 1991, the main groups of stone rows have been protected from the public by fences "to help vegetation growth", When James Miln studied the stones in the 1860s, he reported that fewer than 700 of the 3,000 stones were still standing, and subsequent work during the 1930s and 1980s (using bulldozers) rearranged the stones, re-erecting some, to make way for roads or other structures. In 2002, protesters invaded the site, opening the padlocks and allowing tourists free entry. In recent years, management of the site has also experimented with allowing sheep to graze among the stones, in order to keep gorse and other weeds under control. In June 2023, 39 menhirs still outside the UNESCO protected site were destroyed to construct a DIY store of the Mr. Bricolage franchise, which obtained a building permit from the local town hall in August 2022. The affected stones were located in the town of Montaubin, separate from the primary tourist locations of Ménec and Kermario, which are situated a little over 1.5 km (1 mile) away. The town's mayor, Olivier Lepick, told AFP that he had "followed the law" and pointed to the "low archaeological value" of objects found during checks before the construction process began. He also admitted to being unaware that the site was listed on the Heritage Atlas, despite reportedly presiding over the group that applied for UNESCO status for the prehistoric sites. While Lepick blamed the region's complex zoning situation, the researcher Christian Obeltz claimed that "elected officials in the area and the department are in a hurry to build up anything because once it is classified with UNESCO, it won't be possible anymore". The local Koun Breizh association lodged a complaint with the public prosecutor of Vannes for willful destruction of sites that relate to archaeological heritage. In 2025, the stones, along with 550 monuments across 28 towns and villages in Morbihan, were designated as World Heritage Sites by UNESCO. ==See also==
