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.

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.
