Kasteel van Wideux is a neoclassical water fortress located near the Kleine Herk river in Hasselt, Belgium. Originally constructed as a medieval defensive structure, the castle was devastated by fires in 1468 and 1735 before being reconstructed from 1747 onward in refined neoclassical style with brick and limestone construction. The complex once included a gatehouse, stables, and service buildings arranged around an inner courtyard, featuring symmetrical design, arched windows, and mansard roofs. Today the estate functions as private residential dwellings and a farmhouse, preserved as an important architectural heritage site in the Hasselt region.
