Durocortorum Remis
Reims, the capital of the Remi Prei|m|o = premier. Durocortorum, duro|cortor "place of ?", may have been the site of a pre Roman oppidum but the Celtic town could equally well have been developed after the arrival of J Caesar.

Turnacum
Tournai, the capital of the Menapi in the Late Empire when it replaced Cassel. Turnacum, turno|acum, "eminence|place" was possibly an early Roman military site on the left bank of the Escaut (Schelde) which was the boundary to the Nervi. Initially disorderly, the town expanded at the crossing of the roads from Arras with that from Cassel and was walled in the Late Empire.
