The western centre of France is one of the richest regions of Western Europe in terms of causewayed enclosures from the Neolithic period. To date, more than 300 such sites have been identified. Most causewayed enclosures in the region range in size from some hectares to over 10 ha. Exhaustive excavation of such sites is rarely performed because suc...

Ce travail vise à déterminer l’évolution des conditions d’exploitation du sel autour du site du Pontet au cours du Néolithique récent et de l’âge du Fer par la confrontation des données archéologiques et environnementales. Le site principal du Pontet est un site fossoyé de plateau qui a été occupé principalement durant le Néolithique récent (3600-2...

The earliest monumentality in Western Europe is associated with megalithic structures, but where did the builders of these monuments live? Here, the authors focus on west-central France, one of the earliest centres of megalithic building in Atlantic Europe, commencing in the mid fifth millennium BC. They report on an enclosure at Le Peu (Charente),...

The Centre-West of France, between the rivers Loire and Dordogne, is a geographical area rich in Neolithic causewayed enclosures, with 312 sites referenced in 2020. Most of these enclosures were discovered on aerial photographs, taken by aerial prospectors or by State services such as the IGN, which highlight the cropmarks of the enclosure ditches....

The Chapelles villa in the locality of Grand Fief Chagnaud at Port-des-Barques (Charente-Maritime, Nouvelle-Aquitaine) lies in a remarkable location on a spit of land overlooking the mouth of the River Charente on one side and the Gulf of Brougage on the other. In Roman times, this rural settlement lay in the lands of the Santones whose main city w...

Durant les campagnes 2018 et 2019 à Porsuk – Zeyve Höyük, un travail d’inventaire et d’informatisation du dépôt de fouille a été entrepris, en parallèle avec un travail de numérisation des archives de fouilles. Une prospection géophysique a été menée sur tout le site et a permis la mise en lumière de structures radiales (d’époque hittite ?) et de s...

The NeoArabia project tries to understand how environmental, social, economic and technological factors work in concert to influence settlement and abandonment along a latitudinal transect of 1200 km from UAE to southern Oman. This region was affected by wide north–south variations in the Indo‐Arabian monsoon, marine upwelling activity and eustatic...

L’étude archéologique d’un site est réalisée sur la base d’une fouille, qui est une étude précise sur une ouverture restreinte. En amont de cette opération, la prospection géophysique offre la possibilité de localiser une zone susceptible d’apporter des informations majeures par une cartographie détaillée du site. Ces travaux de thèse se focalisent...

This article focusses on an original magnetic survey protocol and its data processing chain. The use of a high sensitive magnetometer combined with a motorized total station permits production of a magnetic map with a high spatial resolution and a high precision of magnetic and positional measurements. The data processing enhances the final magneti...

Analysis of sediment records and AMS radiocarbon dates are used to reconstruct Quaternary landscapes and palaeoenvironments of the ancient Roman harbour at Narbonne. Capital of the Roman Province Gallia Narbonensis, which extended from the Pyrenees to the Alps, Narbonne was one of the largest port cities in the northwest Mediterranean during the fi...

Since 2005, an interdisciplinary team of research attempts to reconstruct the topography of the ancient port of Narbonne, considered one of the largest ports in the Roman Empire. Begun in 2007, geophysical surveys are one of the pillars of this work. They have evolved over the measurement campaigns in order to adapt to the constraints of the field,...

Le site du Pontet est localisé à 5 km de l’estuaire de la Charente. Il a été identifié en 2009 sur des clichés aériens montrant la présence de 4 fossés discontinus et subparallèles attribués au Néolithique récent/final. Des campagnes de prospection géophysique y sont effectuées depuis le printemps 2015 dans le cadre d’une thèse. Un nouveau protocol...

This paper presents an application of photogrammetry on ceramic fragments from two excavation sites located north-west of France. The restitution by photogrammetry of these different fragments allowed reconstructions of the potteries in their original state or at least to get to as close as possible. We used the 3D reconstructions to compute some m...

Reconstitution of whole ceramics from fragments is a true priesthood for ceramographers. This activity remains mainly handled by manual sketching and can be very time consuming. However, more and more tools and workflows provide digital solutions, based on 3D technologies, to assist such tasks. In this paper, we present an application of photogramm...
