The "ferme castrale" of Hermalle-sous-Huy, located near the Meuse between Huy and Liège in Belgium, is the old farm of the castle of Hermalle and dates from 1642.
In the seventeenth century, the count of Holy Roman Empire Conrad d'Ursel, owner of the Castle of Hermalle, renovated and expanded his property.
The farm was permanently isolated from the forecourt of the castle by a wall and a half turret built at the end of the west wing.
The stone frames of openings differ depending on the period of construction ; some door lintels were also changed in the nineteenth century for the sake of aesthetics.
The place and the exhibition shown, "Old culinary heritage in private collections", received an appreciative audience that influenced the future of the building.
On October 7, 2008, the municipal council Engis voted unanimously for classification to the Walloon Region and the application for registration of the building on the backup list.
