The history of this castle goes back to the 11th century when a first fortification was erected on this spot. We know that the castle was inhabited by Walter de Kefreyn in 1235. This family become extinct when Isabelle de Kefreyn dies without an heir in 1314. We can't find anything about the castle until it appears again in 1354 when it is owned by Wautier de Walzin. He dies in 1385, his daughter Marie marries Gilles de Kemexhe. In 1466 the castle is destroyed by the French army and in 1489 it is again plundered by the Austrian army. 1554 is again a disastrous year. The French army of King Henry II invade the area. The Duke of Nevers installs himself in the castle and burns it down. The year is 1566 when Catherine d'Yve owns the castle she was in 1553 married with Thiry III van Brandenburg. She dies in 1566 and her son Jan van Brandenburg becomes lord of Walzin. His widow Adrienne de Berlaimont restores the castle in 1581. The armorial bearings of the Brandenburg – Berlaimont family still decorate the mantelpieces. The last marquis d'Yve dies without an hair in in 1821 so the castle goes to his widow who gives the castle to her niece Countess de Hamal. She sells the castle to Alfred Brugman in 1850. Alfred starts to restore the castle. In the years 1930 – 1932 there is another restoration done by Baron Fréderic Brugman. His daughter Baroness Albert de Radzitsky d'Ostowick becomes the lady of the house in 1945. Last thing I heard is that the castle was up for sale a couple of years ago. I have no current information about who owns the castle.
Now the fun part is how to get there. As you only can view the castle from the river you have two ways to get there. One is driving up there or you can choose the more fun way and park your car at the train station of Anserremme and hike the dirt path along the left bank of the river Lesse. This way you have to walk about 5km along the river through the forest. Much more fun than driving to the castle. However no matter how you get there to get a good view of the castle you have to cross the river and there is no bridge so you only option is to wade through the river, the river is never really deep, although I'm 180cm and I stood until my middle in the water. Be careful you are not knocked over by a canoe because there are hundreds of them during a nice summer day.
