The castle is located in the charming Ardennes landscape between Waulsort and Dinant, directly on the banks of the Meuse River. It was built on the ruins of an old fortress that was destroyed in 1554. Originally a Renaissance-style manor house, it was enlarged and modified in the 17th and 18th centuries. This former summer residence of the Counts de Beaufort-Spontin boasts a refined and cosmopolitan interior. Its salons were furnished and decorated by the 20 generations who have lived there…here, history comes alive in a magnificent setting. The castle's beautiful classical gardens and their orange trees, some 300 years old, are considered an exceptional heritage of the Parks & Gardens of Wallonia. Their design was inspired by the work of Louis XIV's gardeners at Versailles. Stroll through the labyrinth of arcades and head to the foot of the charming Trianon. The well-structured beauty of these gardens offers a distinctive contrast to the wooded slopes and steep cliffs surrounding the valley. Dogs are allowed here, on a leash, and only in the gardens, not in the castle building. Source: https://visitwallonia.de/de/produit/schloss-freyr-und-seine-garten/9559?cookie_lang=de
