Colonia Trajana
Colonia Trajana is only mentioned in the Antonine Itinerary and the Table. It is on the road from Colonia Agrippinensis (Cologne) to Lugdunum (Leyden). Colonia Trajana is between Vetera and Burginatium. It is agreed that the place is Kellen or Kelln, near Clèves, or Clèves itself, as some suppose.
