Bachle in the city of Freiburg.
They also functioned as rainwater gutter carrying all the dirt from the streets.
In a letter to the Dutch politician, Gaspar Schetz, Erasmus wrote:
Here there is great uncleanliness.
Through all the streets running an artificially-run brook.
With this water the sheets are washed, cleaned the wine glasses, even the cooking pots.
Water streams flowing through cities were more common in the early days.
Many German towns and cities, aside from Freiburg, have watercourses although Freiburgs Bachle are the most famous.
