An old branch of the Rhine river is little more than a city canal here. Historically, this waterway is what gave the area its importance, first as a Roman border, then during the Golden Age as a trade route. Nowadays, river traffic doesn't use this branch and the river just serves to fill the city's canals with water. The area between the Oude Rijn and Nieuwe Rijn is one of the most undisturbed bits of Leiden - go here if you like walking along canals without getting run over by shoppers. On the other side of the city centre (Weddesteeg, Galgewater) is the place where the canals recombine - this is one of the most beautiful spots in Leiden, with a windmill, the old city gate, a small park, and a wooden bridge over the river (see also the image at the head of this article).
