Kromme Rijn

 ( Rivers Of The Rhine–meuse–scheldt Delta ) 

The Kromme Rijn (; "Crooked Rhine", for its meander) is a river in the central Netherlands.

In Ancient Rome times, this northernmost branch of the Rhine river delta was the main distributary of this major European river. Along its banks the Romans built their frontier castellum part of the Limes Germanicus.

Since the Middle Ages, however, the stream lost its importance as it silted up, and eventually it is nearly cut off from the Nederrijn-Lek River main artery. Yet it retained the name "Rhine".

The Kromme Rijn splits off the Nederrijn-Lek main artery at the old town of Wijk bij Duurstede (called Dorestad in the early medieval period), after which it twists and turns through the province of Utrecht, past the towns of Cothen, Werkhoven, Odijk and Bunnik, and ends in the moat of the city of Utrecht.

Originally, the city of Utrecht was built by the Romans at a ford near the place where the Kromme Rijn forks into rivers Vecht (north) and Leidse Rijn (west); the last stretch within the , however, was channelised to form the Oudegracht canal. Rivers Leidse Rijn and Vecht extend from the city moat and are the continuation of the Kromme Rijn.
