Château de la Fenderie is a 17th-century castle in Trooz, Belgium, intimately connected to the region's industrial heritage as a historical metalworking site where iron bars were split into rods using hydraulic mechanisms and water power. Located along the scenic Vesdre river, the castle's infrastructure reflects its dual role as both aristocratic residence and industrial facility, with a water storage basin harnessing the river for power generation. Today, the château serves as a popular starting point for local hiking trails, attracting outdoor enthusiasts exploring the natural and industrial heritage of the Liège province.
