history

From the Middle Ages, the operation of a mill on Ohbach ("lower mill") can be traced, which gave it the name "Milenbach" at the time. A second mill ("Olligsmühle"), next to the so-called "Olligsberg" near Selhof, was added in 1716 and was first converted in 1719 into an oil mill and after 1764 into a grinding mill . Further up in the then Honschaft Beuel, another oil mill was built in 1782, which was called Grendelsmühle , from 1851 it served as a stone mill and later as a sawmill . A fourth mill operated by Ohbach was completed in 1849, but like the first three, it went out of service at the beginning of the 20th century at the latest. Between the districts of Beuel and Selhof, the original course of the stream was changed by relocating it to the north. During the First World War, the residential building of the lower mill on Ohbach was demolished to widen Bahnhofstrasse at the confluence with Steinstrasse. The mill buildings on today's mill path were preserved. In the vicinity of a fountain ("Fuck") on the Anna Path, the brook used to be called Fuckenbach , the bridge above it was called the Fuckenbrücke and the ridge from the then Antoniusstift to Linzer Straße Fuckenberg .

“The name Ohbach seems to have been invented by some surveyor in recent times. He was and is completely unknown to the local people. "
