Château des Cailloux stands as a striking example of neo-Renaissance architecture in Jodoigne, Wallonia. Built between 1881 and 1883 by Hector Defoër, an Egyptian financier, the castle features distinctive architectural details typical of its era. Following a devastating fire in 1952, the roof was rebuilt in simplified fashion. After World War II, the Belgian state acquired the property and established a boarding school in 1950, with the Sacred Heart Sisters' school taking over operations in 1960. The château remains a notable historical landmark in the region, representing the evolution of Belgian aristocratic residences during the industrial era.
