This oak, 200 to 300 years old, would have been used by the German army during the First World War as an observation post. The panel states: "The soldiers could thus observe the artillery and enemy movements. We can still observe some of the iron bars which would have been inserted into the trunk in order to constitute a ladder. The tree having continued to grow, the majority of the bars have been absorbed by the bark."

Remarkable century-old oak, having participated in the history of the First World War. It is easily accessible by bicycle. Which is not the path that goes deep into the forest.

Difficult to drive on the site at this time because of the "luxuriant" vegetation. Access to the karting level is blocked by padlocked gates.

Beautiful slag heap accessible to the most athletic 3 switchbacks without a plateau to reach the top and admire the beautiful view of the Harnesien and the Carvinois and other summits of the slag heaps that surround it.
