When I was young, I used to climb from the bottom of the cave and we would reach the very top of the site. With a beautiful panorama of the city.

It's a very beautiful place for a walk. You can start from the Trixhes, go down a small path along the quarry. When you get to the bottom, you arrive at the Carrière des Roches. From there, you pass by two sides with different rocks. If you continue, you arrive in "Houlbouse" street. And finally, at Chokier. Very beautiful hike. To do with dogs and especially children.

A castle built as a country retreat between 1717 and 1727 in the Louis XIVth style, then popular in the Meuse Valley, belonged to the Church of Liège. A fortress existed on the same site as early as 900. The estate also features a French-style garden with corner towers, and adjacent to the castle is the limestone castle farm. Now privately owned and in need of renovation.

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.
