Château d'Ordange in Seraing is a historic fortress with origins tracing back to 1414, rebuilt after being damaged during medieval conflicts. The castle retains its medieval character with an enclosed layout, protective moat, and two distinctive circular towers from the 15th or 16th centuries framing the entrance. Notable interior features include old stables and a chapel with vaulted ceilings adorned with remarkable wall paintings in the sacristy. Now serving as part of the city's cultural programs, the castle operates as a venue for artistic expression and creative workshops, preserving its heritage while supporting contemporary cultural initiatives in the community.
