Oude Rijn (Utrecht)
Satellite close-up of the Utrecht region showing the Leidse Rijn-Oude Rijn stream (d).
The city of Utrecht was founded at a ford near the fork of river Kromme Rijn into the Vecht to the north, and the Oude Rijn to the west. Of the original fork, little remains today and both Vecht and Rijn start from the city moat. For the first few kilometres of its course, the river is channelised and known as Leidse Rijn ("Leyden Rhine"). It flows past the cities of Woerden, Alphen aan den Rijn and Leiden towards Katwijk. Here, the Oude Rijn originally flowed into the North Sea, but the stream has been closed off by a sluice complex regulating its water level.
Many of the cities and villages along the Oude Rijn are of Roman origin, stemming from border-guarding castella and castra.
