Les mégalithes de Saint-Just (Ille-et-Vilaine) et la fouille des alignements du Moulin de Cojou

Abstract

A rescue dig, on a part of the Cojou megalithic alignments at Saint-Just (Ille-et-Vilaine, Brittany, France), showed a long and complex fréquentation of the site. It began by a series of large hearths dated between 4940 and 4100 B.C. The standing stones were erected at least in two phases separated by the building of a stone «causeway», itself partly covered by a mound which yelded remains of beakers of spécial interest and a large Early Bronze Age urn, dated 2780-2180 B.C. This excavation provided also the opportunity of a general survey of the megaliths of this parish, which revealed severely damaged by comparison with the old descriptions.

Landscape Evolution and Human Settlement in the Iroise Sea (Brittany, France) during the Neolithic and Bronze Age

“…However, our research shows a strong geographic concentration of burial remains which helps to refine the distribution patterns at a regional scale. For the first part of Middle Neolithic, the morphology of the long barrow excavated on Ledenez Vihan Qué-ménès shows strong analogies with that of other long barrows excavated in Brittany (Ramé 1864; Giot & L'Helgouach 1955;1956;Giot et al 1995;Briard et al 1989;Briard 1992;Le Roux et al 1989), the geographically closest example being that of Souc'h in Plouhinec (Le Goffic 2004). Radiocarbon dating (UBA-16738, 5624 ± 29 BP) of a sample from the foot of one of the standing stones surrounding the monument calibrates to 4520-4366 cal BC (2 sigma).…”

Modeling Prehistoric Populations: The Case of Neolithic Brittany

“…This is suggested by radiocarbon dates from Saint-Just ( Briard et al 1995, 54-56;Le Roux et al 1989), and by the relation of certain coastal menhirs to lower sea-levels (Giot 1990). Equally, it is clear that undecorated menhirs continued to be erected during the 4th and 3rd millennia BC, and probably later (e.g.…”

Les pierres dressées de la forêt du Gâvre (Loire-Atlantique) : nature et origine des matériaux, premiers éléments de chronologie (14C, OSL)

“…Mais les contre-exemples à propos de ces constructions sont encore plus abondants et tempèrent en définitive toute généralisa-tion et tout déterminisme géologique ou pédologique. Si le phénomène tectonique observé au Gâvre a très nettement influencé l'emprunt direct des roches et l'orientation de leur implantation (après tout, tectonique vient du grec τέκτων ou tektōn signifiant « bâtisseur »…), le site peu éloigné du Moulin (Saint-Just, à 15 km au NO) témoigne de l'importation de blocs de quartz filonien sur une distance de 3 km, avant d'être dressés et intégrés à trois files d'orientations distinctes (Le Roux et al, 1989), nous rappelant ainsi que ces architectures dépendent toutes d'un modèle anthropologique pour les animer.…”
