The megalithic architectures of Europe
\"Megalithic monuments are among the most striking remains of the Neolithic period of northern and western Europe and are scattered across landscapes from Pomerania to Portugal. Antiquarians and archaeologists early recognised the family resemblance of the different groups of tombs, attributing them to maritime peoples moving along the western seaways.

Megalithic Architectures provides new insight by focusing on the construction and design of European megalithic tombs--on the tomb as an architectural project.

The large slabs that were employed, often unshaped, may suggest an opportunistic approach by the Neolithic builders, but this was clearly far from the case. Each building project was unique, and detailed study of individual sites exposes the way in which tombs were built as architectural, social and symbolic undertakings.

The Megalithic Architectures of Europe
Megalithic monuments are among the most striking remains of the Neolithic period of northern and western Europe and are scattered across landscapes from Pomerania to Portugal. Antiquarians and archaeologists early recognized the family resemblance of the different groups of tombs, attributing them to maritime peoples moving along the western seaways. More recent research sees them rather as the product of established early farming communities in their individual regions. Yet the diversity of the tombs, their chronologies and their varied cultural contexts complicates any straightforward understanding of their origins and distribution. Megalithic Architectures provides new insight by focusing on the construction and design of European megalithic tombs – on the tomb as an architectural project. It shows how much is to be learned from detailed attention to the stages and the techniques through which tombs were built, modified and enlarged, and often intentionally dismantled or decommissioned.

Structural functions and architectural projects within the long monuments of Western France
Particularly over the last few decades, the megalithic monuments of Western Europe have been extensively studied. Topics have included: the large stones used in their construction which sometimes bear symbolic markings; the diversity of the funerary practices that are often associated with such structures; and their role as monuments serving as places of memory for the living, as markers in the landscape, and as indicators of social complexity. More rarely, they have been considered as real architecture representing the first stone buildings in this part of the world. Surrounded by dry stone walling – sometimes reaching several metres high –
Another brick in the wall: fifthe millennium BC earthen-walled architecture on the Channel shores
The west European Neolithic is famed for its funerary and ceremonial monuments, but the evidence for houses is sparse. Can this be explained by the materials of which they were built? On the northern coast of Brittany, the site of Lillemer rises from the surrounding marshes and presents abundant evidence of Middle Neolithic occupation, contemporary with the passage graves of the region. Surprisingly, their evidence includes the remains of collapsed earthen-walled structures, providing the northernmost example of this type of architecture in a Neolithic context and a possible explanation for the invisibility of much Neolithic domestic architecture.

Phenotypic characterization of chronic inflammation in a rare case of endobronchial carcinoma
This report presents a phenotypical characterization of the immune cell infiltrate in a rare case of endobronchial carcinoma. A patient initially treated for an adenocarcinoma of the esophagus developed an endobronchial carcinoma surrounded by gastric metaplasia distal to a suspected gastrobronchial fistula, 11 years after esophagectomy. Our hypothesis is that the sustained exposure of the bronchial mucosa to a mixed acid and pancreatobiliary refluxate led to chronic inflammation and promoted malignant transformation. We performed an immunohistochemical study of the tumor microenvironment evaluating the density of CD3⁺, CD8⁺ T lymphocytes, CD20⁺ B lymphocytes, CD68⁺ macrophages and FoxP3⁺ regulatory T cells. Quantification of immune cell density was completed using a novel software-based analysis method. Our results suggest that, within all the tissues analyzed, FoxP3⁺ regulatory T cells were present at their highest density in the malignant and metaplastic tissues. The endobronchial metaplasia biopsied several years prior to the detection of the endobronchial adenocarcinoma was already densely infiltrated by B cells and macrophages, when compared to the immune cell infiltrate of the endobronchial carcinoma. Altogether, these observations support the current understanding of carcinogenesis promoted by chronic inflammation.

Natural and artificial colours: the megalithic monuments of Brittany
Megalithic art is a well-known feature of the Neolithic chambered tombs of Atlantic Europe. The surviving evidence consists largely of carved motifs, and, until recently, painted megalithic art was thought to be restricted to western Iberia. Recent discoveries have expanded that distribution, assisted by new methods of detection, recording and analysis. The discovery of painted motifs at Barnenez in Brittany, reported here, marks a breakthrough and raises the possibility that many megalithic tombs in north-west Europe were once coloured as well as carved. Similarities in motifs and techniques also point to the likelihood of direct connections with Iberia.
A southern viewpoint
Diffusionist theories for the Neolithic in western Europe were completely reversed when the first radiocarbon dates were obtained from Breton sites such as Carn and Barnenez (Giot 1960). Those diffusionist theories had identified Millares as the place of origin of west European megalithic structures, emanating from eastern influences. Moreover, at that moment another tradition began; one of regional studies that are only now beginning to be superseded. Diffusionist ideas have been in vogue for such a long time that they have left a powerful legacy, especially in the southern part of the Atlantic façade. There are even differences between the
Megalithic monumentality in Africa: from graves to stone circles at Wanar, Senegal
The World Heritage Site of Wanar in Senegal features 21 stone circles, remarkable not least because they were erected in the twelfth and thirteenth century AD, when Islam ruled the Indian Ocean and Europe was in its Middle Ages. The state of preservation has benefited the exemplary investigation currently carried out by a French-Senegalese team, which we are pleased to report here. The site began as a burial ground to which monumental stones were added, perhaps echoing the form of original funerary houses. Found in a neighbouring field were scoops left from the cutting out of the cylindrical monoliths from surface rock. While the origins of Wanar lie in a period of state formation, the monuments are shown to have had a long ritual use. The investigation not only provides a new context for one of the most important sites in West Africa but the precise determination of the sequence and techniques used at Wanar offers key pointers for the understanding of megalithic structures everywhere.
L’Art et la manière : Approche technologique des céramiques de dépôt dans le mégalithisme sénégambien – Le cas de la nécropole de Wanar (Sénégal)
Among the many characteristics of the Senegalese and Gambian megalithic phenomenon, the deposition of pottery on the eastern edge of funerary structures is a recurrent practice present throughout the excavated sites. In the western part of the megalithic area, ceramics are generally located between the standing stone-circles and one or more frontal stones erected east of monuments. With the exception of morphological and decorative aspects, no technological studies have ever been conducted on the pottery from these deposits. Such an approach has now been taken to the analysis of around forty ceramics from deposits at the site of Wanar — about as many as are available from the deposits of all other Senegambian megalithic sites. The results demonstrate the range of technical choices mobilized in the shaping process. The high degree of finish on the vessels also suggests an important added value to the material culture which participated in the monuments’ ritual function.
