The Roman Iron Age to Migration Period riverside market of Elsfleth-Hogenkamp, district of Wesermarsch, forms the focus of the current volume. It has been known about since the 19th century, thanks to pottery found on the ground surface. Yet it is only through the analysis of objects systematically recorded using metal detectors that the character of the site became clear. Over several centuries, this was a place whose economy was oriented towards the exchange of goods and craft production, and whose users had good connections to the Roman Empire. Yet for a long time, it remained unclear whether and how the area had been built on, whether all parts of the Hogenkamp were in use simultaneously, and not least at what technological level which of the different craft activities were carried out. These questions could only be tackled in a project jointly applied for and run by the Lower Saxony Institute for Historical Coastal research and the Deutsches Bergbau-Museum Bochum between 2015 and 2019, and funded by the German Research Foundation. This volume makes the results of our excavations and the typochronological analyses of the finds and features available for wider discussion. The material clearly shows that during the first millennium A.D., the riverside market, as well as the confluence of the Hunte and the Weser, were of crucial importance for inter-regional communication and exchange networks.
