This peaceful oasis is well hidden behind the town hall. it used to serve as an orchard and yard of the aldermen's house. Now it is a beautiful piece of green in the middle of the city. You can admire the ancient trees and the statue of the Ropieur, which depicts a boy who splashes passers-by with water from the fountain.

It is at the confluence of the Trouille and the Nouvelles river that this waterfall bridge was born. Originally there was a mill, which was turned into a tannery after the First World War. Today it is a bucolic place surrounded by nature.

Behind the town hall is the magnificent Jardin du Mayeur. It is the ideal place to enjoy the carillon of the belfry. Le Jardin du Mayeur was created in the 1930s. Do the math: some of its trees are therefore three-quarters of a century old!

This is a summit climb. Especially on the adventurous side. There are ropes there to hoist you up. The other side is a nice wide walking path. In my opinion, the most beautiful slag heap on the GR 412.

The Crachet slag heap is a Site of Great Biological Interest (SGIB). It is also part of the Natura 2000 network to protect its exceptional fauna and flora. Located a stone's throw from the SPARKOH science museum! (former PASS), the slag heap is a fabulous educational tool which regularly welcomes school visits but also families looking for calm and nature. Thanks to its marked and well-equipped paths with stairs, small bridges, duckboards and ropes, its ascent is easy despite a difference in altitude of around 70 m. Relatively wooded, the Crachet sometimes gives way to magnificent grassy wastelands and a few ponds which encourage the development of great biodiversity. Its summit, located at an altitude of 140 m, offers a beautiful panoramic view of the Borinage slag heap range as well as the SPARKOH! site, built by the architect Jean Nouvel. In this place, the ground is adorned with red and black. Smoke can even be observed in certain places because the heap is still burning more than 60 years after the closure of the site. coal mining. https://www.destinationterrils.eu/nl/terril-du-crachet

The bridge/waterfall was built at the confluence of the Trouille and the Rivière de Nouvelles. In the early, late 12th century, there was an old domanial mill on the site, the Moulin-au-Bois. Imagine that there was a dike on the site of the current street, a large fish pond on the site of the pasture, and that there were three mill wheels instead of one. This is what the site used to look like. In 1823 the mill was sold by the city of Bergen and after the First World War it was converted into a tannery. The only remnant of the mill that is still visible today is part of the wall along the street, just before the bridge. Still, the waterfall remains one of Hyon's most symbolic places.
