The castle of Freÿr with its gardens in the style of Le Nôtre is located on the left bank of the Meuse, between Waulsort and Dinant (province of Namur, Belgium). They form one of the most magnificent natural sites in Belgium. It has been classified as one of Wallonia's major heritage sites.

Dating back to the Middle Ages, Freÿr was a keep given in fief by the Count of Namur to Jean de Rochefort Orjol in 1378. His granddaughter Marie married Jacques de Beaufort in 1410. Their descendants have kept the estate until the present.
The castle is representative of the interior of a nobleman's summer residence of the 18th century. It features many original elements such as the impressive main hall with wall paintings by Frans Snyders and a ceiling covered by Louis XV frescoes, or the chapel with its Regency wooden panelling and its Baroque altar.

The rooms contain the ancient furniture of the Dukes of Beaufort-Spontin as well as traces of history left by royal guests (Louis XIV of France, Archduchess Maria-Christina, eldest child of Empress Maria Theresa of Austria, King Stanislas I), and the living memory of 20 generations, among which is a delightful children's coach (18th century) that won the first prize at Paris World Exhibition (1889).

At Freÿr the Coffee Treaty or Treaty of Freÿr (1675) between France and Spain was signed, and the Treaty of the Borders between France and the Prince-Bishopric of Liège (1772) was negotiated. At this time Louis XIV stayed here as the guest of Jeanne d'Harscamp, Dowager Duchess of Beaufort-Spontin
