Town streams (S11QR2)
In around 1320, Duke Rudolf I ordered the stream known as Rischebach to be diverted into the town in order to power the mill. When the flow was no longer sufficient by the late-14th century, another stream (‘Stagnant Stream’) was also rerouted into the fortified town. Brewers, tanners and dyers as well as fishmongers all used the open streams to keep their wares fresh. However, with the streams also being used for sewage disposal, during defortification in the 19th century they were finally diverted underground, not least for hygienic reasons. The historical streams were gradually returned to the surface in a project starting in 2002.
