The construction of the castle started at the end of the 12th century and ended the beginning of the 13th. It was a plane fortress surrounded by deep large moats, which were filled up a long time ago. The castle with two impressive keeps was built to defend the Namur County against the Dukedom of Brabant. The curtain wall is strengthened with 6 round towers built out of big red 'moellons' (a special kind of brick) The only entrance is located on the north side and is defended by two round towers. At the end of the 17th century the castle was partly destroyed by a fire but rebuilt immediately. The current main living quarters are from the end of the 18th century or beginning of the 19th century. The castle was almost demolished. However, doctor Geerts bought the building and started with the restorations to preserve this peculiar and impressive castle. The castle is open for visits on certain times like the heritage days in September but you can view this castle that rises with his gloomy silhouette out of the meadows from the public road. Groups can also visit on appointment.
