Copper beeches, tulip trees, ancient oaks, giant redwoods and other wonders of nature makes these landscaped gardens (45ha) the finest arboretum in Wallonia. You will see sculptures by Belgian artists Victor Rousseau, Constantin Meunier and Jef Lambeaux, as well as one of the four bronze casts of Rodin's The Burghers of Calais. In the place of the old château, which was destroyed by fire, there is now a modern museum.
