Wijk bij Duurstede
Due to its location at the junction of the Rhine and the Lek (and its predecessor), Wijk bij Duurstede was important to both the Romans and the Dutch. The Romans built a castellum near the harbour and likely named it Levafanum. In the time of the New Dutch Waterline, an inundation lock was built that brought the water from the Lek to Utrecht. Border markers can still be seen along the Kromme Rijn, which indicated that it was a military river. The river also formed the border of the Roman Empire.
