The remains of the fortress of Samson are the ruins of an ancient fortress perched on a rocky promontory overlooking the Samson and the Meuse. There you will find the remains of two towers and a wall which testify to the ancient prestige of this castle, which was one of the strongholds of the county of Namur and resisted attacks by the Normans in the 9th century. The fortress was demolished in 1691 on the orders of King Charles II of Spain and its stones were used to build many houses in the neighboring villages of Thon and Samson. You can admire the ruins from the valley entrance, but the site is not open to visitors. However, you can enjoy the natural beauty of the region and explore the charming village of Thon-Samson, which is ranked among the most beautiful villages in Wallonia.
