For 3 years, a workshop of UMR 8164 Halma organized in collaboration with universities and other institutions in Villeneuve d'Ascq, Amiens, Beauvais, Reims, Caen and Tours, devoted itself to the fortified cities of the late Antiquity of north of Gaul.
Following these exchanges, it seemed appropriate to bring together in one volume the essential elements of the best-known urban fortifications, and especially those which have been the subject of studies, archaeological interventions or recent observations.
Members from archaeological services, community services, the CNRS and the universities of Reims, Caen or Tours, participate in the development of this book (thirty contributors).
In connection with the DRAC Hauts-de-France, the YuSit team is proud to participate in the writing of this scientific publication that brings a new light on these works of the late antiquity of northern Gaul!
