Saint Hadelin's Church

Highlight • Religious Site

Saint Hadelin, known as Hadelin de Celles who died in 692, is the companion of Saint Remacle, founder of the abbey of Stavelot in 662. It is on June 16, 747 that his name appears for the first time in the diploma of Carloman , eldest son of Charles Martel who gives this stronghold to the abbey of Stavelot. In 891, the monks of Stavelot, fleeing from the Norman invasions, report that they took refuge in 883 on a promontory and that they were saved by a miracle. The Vita Hadelini was written in 1007, which explains the choice of this saint as patron of the parish, long owned by the abbey of Stavelot. There were never more than fifteen houses.

The village was formerly called Soumagne-Saint-Hadelin as opposed to Soumagne-les-Moine, the old name of the current village of Soumagne-Bas.

View over the Vesdre Valley

Highlight • Viewpoint

In this season the trees are completely bare and the view over the Vesdre valley is truly breathtaking. You overlook almost 180 °! If the weather is right, it's just wonderful!

Fenderie Castle

Highlight • Castle

From 1583 and until the 1960s, workers and craftsmen worked in these forges to split iron bars into rods and rods, forge nails, treat sheet metal and flat iron for armory and utensils, drill gun barrels.

The peak of the arms industry took place throughout the valley between 1880 and 1890. There were then 18 drilling factories on the Vesdre, most of them in Nessonvaux.

Crossing small hamlets: on the banks, Coucoumont, Hansez, Saint Adelin, wood of the fenderie and the magnificent little village of Forest. Signposting not great, so 2 small unforeseen round …
