history

Around 1610, the Godesberger Bach was extended in a canal along the then Cöln-Mainzer Landstrasse (later Coblenzerstrasse ; today Bundesstrasse 9 ) to Bonn. Initially running along the east side of the street, he only left it at the Hofgarten , where he fed a water basin from the 18th century . This branch of the Godesberger Bach operated some mills , including the electoral mill in the area of today's opera house and in 1860 one of the Zuntz companies. Their own bridges linked the resulting 19th-century villas in the Bonn Rhine with the Coblenzerstraße, prior to the current site of the Foreign Ministry at the beginning of the diagonal to the towpath leading Plittersdorfer alley a public (as of 1846). At the end of the 1880s, the artificially created stream was removed and a sidewalk was built in its place. The former channel bed of the Godesberger Bach was used from 1892 by the then newly opened railway line from Bonn to Godesberg .

Flood risk

The Godesberger Bach regularly floods when there is heavy rain and, together with the surrounding area, is one of the flood areas designated by the Cologne District Government.
