Description | Annual report on archaeogeophysical prospection on oppidum Bibracte/Mont Beuvray (on Grandes Portes, la Terrasse and la Chaume). The geophysical surveys carried out at Grandes Portes showed only sporadic traces of occupation and revealed very little of the first rampart and its gate. At the Terrace, magnetic surveys did not allowed to detect potential archaeological structures due to the strong magnetism of the subsurface rock. Some ditches were spotted by ground penetrating radar as well as a few buildings were visible only partially on the terraces of the southern slope. At La Chaume, finally, ground penetrating radar enabled highlight the ditch spotted in 2012, which seems disturbed by the presence of masonry located at proximity. Geophysics, which clearly presents greater potential in this part of the site, should be continued in the future, especially with ground penetrating radar. |
