The Genneperhuis was a castle and fortified fortress on the Niers estuary in the Meuse near the town of Gennep near Milsbeek. Until 2009 there were hardly any ruins, only the crown work and elevations in the landscape still give an impression of the size. The area has the status of a protected monument.
When you ride the gravel bike path next to the Niers (from Gennep to the mouth of the Niers in the Maas), a visit to the Genneperhuis is definitely worth it
