Solvay Castle

The Castle is a chateau situated in the region of La Hulpe, Walloon Brabant, Belgium. This was worked by Marquis Maximilien de Bethune. Jean-Jacques Arveuf-Fransquin of France and the Belgian planner Jean-Francois Coppens 1799– 1873 were given the assignment of building the manor, which was finished in 1842.

In the late nineteenth century, the house and bequest were procured by the Ernest Solvay, and have since been known as the Domaine Solvay. Today the property is claimed by the territorial legislature of Wallonia, and is named a "Remarkable Heritage Site in Wallonia." The grounds are available to the general society.
