= Cassel = A town in the Nord Department of France. Cassel stands on Mont de Cassel a prominent hill in the Flanders plain. It seems to be a Roman foundation built to serve as the urban centre of the Menappii. Its Latin name was "Castellum menapiorum". Cassel has developed from "castellum" following Germanic phonetic rules. Many Roman roads converged on Cassel and several are easily picked out today from the hill top.
