The Château de la Grange Fort or Château de la Grangefort is a 15th-century French castle located in the commune of Les Pradeaux, near Issoire, in the Puy-de-Dôme département of France.
It dates from the 15th century but has been destroyed and rebuilt several times. In the 19th century, it was restored and embellished by Viollet-le-Duc. It was converted into a campsite and guest house by Van Bronkhorst, an aristocratic Dutch family originally from Hengelo (Gelderland), who bought the site in 1985.
