The House of Beaufort-Spontin is a noble family which held prominent posts under the Holy Roman Emperors in the Austrian Netherlands, their family seat having originally been in Namur. The most notable member of the family was Frederic August Alexander of Beaufort-Spontin, who became the first Duke of Beaufort-Spontin in 1782. Cadets bear the title of Count or Countess. The members of this family now reside in Austria, but their origins are in territories in what is today Belgium.

The Castle of Freÿr with its gardens in the style of Le Nôtre is located in Wallonia on the left bank of the Meuse, between Waulsort and Dinant. They form one of the most magnificent natural sites in Belgium. It has been classified as one of Wallonia's major heritage sites. It is often called a greatly reduced Versailles. Originally a Renaissance castle, it was extended in the 18th century and was once the residence of dukes and their royal guests. It has gardens including orange trees. The more than three-hundred-year-old orangeries are the oldest in the Low Countries.
