Lors du 21th annual meeting of the European Association of  Archaeologists, Philippe Fajon présente la communication suivante :"Paris – Rouen – the Sea : an old story of over 2000 years" In 1998 and 2008, we have made a compilation of many informations about the « Chaussée Jules César » (Île-de-France and Normandy), the name given to the main road joining Paris to Rouen during the Antiquity. Since this time, new datas and new methods ask us to revisit the concept of this physical link on the north side of the Seine valley. Preventive archaeology brings us the proves that the problem of understanding a main road like this one is not so simple. So, we decided to go back in this study with new tools : satellite photos, remote sensing, GIS, LIDAR, archegeography, long time range and multi-scales). Various excavations show us the possibility to connect short segments of the « chaussée Jules César » with oppida. They also bring us a better understanding of the different ways to cross through deep valleys, and knowledge of land survey. Finally, they give us temporal limits for the use of the track, path or road, sometimes still in use today like a motorway. These collected facts could indicate that the long way along the Seine valley was built by sections on the bases of pre-existant elements, and its evolution depended of economical context and large strategies. This essay aim to recognize the kind of relation existing between human settlements, the landscapes and the "Chaussée Jules César", which still holds a major axis role in structuring the landscape from Paris to the Seine estuary.Site web du congrès
