Freyr or Frey is one of the most important gods of Norse religion. The name is conjectured to derive from the Proto-Norse *frawjaz, "lord". Freyr was associated with sacral kingship, virility and prosperity, with sunshine and fair weather, as well as was pictured as a phallic fertility god, Freyr "bestows peace and pleasure on mortals". Freyr, sometimes referred to as Yngvi-Freyr, was especially associated with Sweden and seen as an ancestor of the Swedish royal house.

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.
