This slope, where the ravine was created, is a Rhine terrace. This was once the bank of the Rhine.

An exciting route through a ravine (sloping from the direction of Butzheim); partly bad road conditions. The small cave passages in the cliffs are particularly interesting. Information boards are set up, you should take a little time.

The path east of Butzheim is the most important ravine in the Rhein-Kreis Neuss with a total length of two kilometers and in parts eight meters deep. It was formed over the centuries because iron-shod wooden wheels used to leave deep tracks in the loess. In addition to the permanent use by handcart users, stable loess soil, high precipitation intensity and a certain slope contributed to the fact that this natural monument could arise.

<< Natural Monument Hohlweg am Galgenberg >> "... A ravine that was created by heavy rainfall after the Ice Age. The predominantly westerly winds blew clay and marl into our homeland and a fertile loess layer formed. This makes the monument very valuable in terms of vegetation geography. Plants that grow on the Lower Rhine almost are extinct here. Eg the black knapweed, real sheep's wings and mountain sanddrops, to name a few. A Roman road is said to have passed through this ravine in the past, from Aachen to Neuß. The gallows of Odenkirchen are said to have stood here in the Middle Ages. A person sentenced to death by the magistrate's court had the verdict read out again by the court clerk under the gallows. Then the bailiff broke a white stick and threw the pieces at the feet of the death row inmate with the words: As true as these two parts of the stick can no longer be brought together, as true you deserve the death penalty according to the law and I surrender you to the executioner in the name of the prince. (Hence the expression; over him the staff was broken.) But now the nicer side of the natural monument. There is a hiking and biking trail around this ravine, which is overgrown by the way. Since this area is the highest point of Odenkirchen, you have a fantastic all-round view and up here you can experience the sunrise and sunset. No streets all around, no noise, little hustle and bustle, pure peace. ..." https://www.lieblingsplatz-niederrhein.de/location/naturdenkmal-galgenberg/ https://www.geocaching.com/geocache/GC1AB5Y_der-weg-am-galgenberg?guid=d7616fd5-8d99-4016-a11b-403c3387213e
