The complex originally consisted of four caves, some of which have now disappeared due to natural collapse and the proximity of quarries. The caves have been protected as cultural heritage in Wallonia since 1978 and have an exceptional status due to their scientific value. Although the caves themselves are currently not open to the public, the site remains an important archaeological and natural history location that visualizes the evolution of humanity.

Unexpected spot in the middle of the park, next to a viewpoint over the city (let's see if we can still see that far when the trees have turned green...), a reminder of a time when the walking routes were punctuated by https://www.dogwhistlings.com

This is a cave I used to visit a long time ago. Before, you could start at the very bottom and work your way up to the top of the quarry. Now, I don't think that's possible anymore.

Although the caves are no longer accessible, they are worth the detour for their unexpected beauty. The red earth blends perfectly with the gray of the rock walls and the green of its abundant ivy. There were originally four caves on this site. The first disappeared due to limestone mining between 1890 and 1900. Exploring the Cockerill quarry massif, Philippe-Charles Schmerling discovered four caves on the site called Trô Cwaheur (= cut, tear). In the second cave, he unearthed two human skulls in 1829, one said to be Cro-Magnon and the second a Neanderthal child. The bones were associated with extinct fauna and presented the same state of preservation. At a time when biblical theory still prevailed, he began to prove the appearance of humans on earth more than 4,000 years ago. But, misunderstood, it would be necessary to wait for the discoveries made in the Neander Valley, in Germany, to see his thesis confirmed. It was a close call for "Neanderthal man" to be called "Awirs man". The site belongs to the Société Carmeuse and has been classified since 1978. The ditch that can be seen on the site is due to a subsidence of the ground following the exploitation of alum. Alum was exploited in this place from 1580 until the middle of the 18th century (around 1740).

In 1829, the Dutch physician Philippus Schmerling found prehistoric remains here. He discovered the Neanderthal man before Neandertal would give it its name after similar finds there in 1856. The caves in which the bones were found are no longer accessible. The area is still known as the site des Grottes Schmerling.

Coordinates: 235.87/139.12/85 The cave is located on the Esneux-Tilff road, on the right bank of the Ourthe River, 1 kilometer before entering Tilff. The large entrance is approximately 20 meters above the road, at the foot of a very steep limestone cliff. This cave has been known for a long time: it was discovered during quarrying in 1837. In the 1960s, the "Réseau Lemaire" was discovered; an upper level with beautiful calcite pools and a lake. Source: https://www.scavalon.be/avalonnl/fiches/fich23.htm
