Michel Raulier: The Nail Tree of Stambruges Tree worship in our region is very ancient. Proof of this is the discovery in Blicquy, in the place called "Ville d'Anderlecht," of a set of 120 posts up to 90 cm in diameter. These may have served as supports for offerings, as evidenced by the numerous iron pins found in the filling holes. This could correspond to an artificial sacred grove housing deities, similar to Lucan's description of petrified forests in Pharsalia. In the past, trees, with their longevity and majestic shape, aroused a sense of sacredness in the minds of our ancestors. They were also believed to be capable of helping people solve their problems, particularly health problems. Many customs exist: walking around the tree, driving nails to fix the ailment, and tying cloths or fabrics to bind it. These trees were often Christianized by the installation of religious images or a chapel nearby. One example among others is that of Notre Dame de Foy. In Foy, near Dinant, a woodcutter discovered a 15th-century statuette in the heart of a very ancient oak tree in 1609. Long forgotten, the figurine bearing the image of the Virgin had been placed in a niche carved into the trunk. Over time, the wood completely covered it and erased its memory. In Stambruges, there is one of these remarkable trees, and beside it is a chapel, called "the chapel of Erconpuch" or, by another name, "the chapel of Arc-au-Puche," dedicated to the Virgin Our Lady of Arc-au-Puits, formerly called the Virgin of the Woods.

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.

There are two viewing huts on the route. But especially many ornithologists. This must clearly be a special place!

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.
