Through pastures and meadows which flows from here to the northeast. On Good Hanbruch along it flows through two retention basins, to be introduced at the junction Pott Miihlenweg / In Johannistal into the sewer system of the city.

History

The historical course of the locust Bach is largely its current course. In its upper reaches it earlier but more to the left and right. In the Middle Ages, he joined the Pfaff tower in the city and then ran through the valley northwest of the market hill. Before joining the city, he drove the squire mill located near the Junkerstors.

Previously, the creek was not exactly along the cable trench, but just north of it, such as along the present road Sandkaulbach.

Originally the Johannisbach united only at the site of the Willy -Brandt -Platz, where in the Middle Ages was the operated among others from the family amya Pletsch mill and now the ball fountain, with the Paunell and a little further to the emperor square, with Pau. North of the square Emperor left the united streams of the medieval town by the water tower and ended shortly thereafter in the worm.

The Johannisbach originally served as a sewer of the medieval city. Between Neutorstrasse and Kölnmitteltor the moat was filled in front of the inner city wall with water from the Johannisbach.

At the siege of Aachen in 1248, as the outer city wall was not yet begun, William of Holland Johannisbach, Pau and Paunell let dam and flooded by a large part of the urban area in order to force Aachen to the task.
