Nijmegen is an ancient city founded
on the south bank of the river Waal about ten kilometers downstream from the split in the Rhine (Rijn) as it goes delta, just inside the eastern border of The Netherlands.
Nijmegen stands at the foot of a Pleistocene terminal morraine, and at 32 meters in elevation, the main old city is well above the delta flatland which probably explains its great antiquity.
The Romans moved in amongst the Batavians.
Nijmegen became an important Roman trading and a military post, then an official municipality at the northern extent of the empire.
