Hauteroche ('High Rock') is a ruined 14th-century castle, destroyed after a siege in 1554, in the village of Dourbes in the municipality of Viroinval, province of Namur. It is situated on a ca. 50 meters high, rocky promontory, looking out over the valley of the Viroin river. The isolated site of the castle is separated from the plateau by a large, hand cut ditch. It has a square keep with 2.5 meter thick walls and it would originally have been at least 13 meters high.
